Romance, Identity & Ratings Tags on AO3

A canonical tag for characters with no gender, used for human agender representation and for entities (AIs, constructs, cosmic beings) whose genderlessness the author treats as identity rather than absence. It is precise where Nonbinary Character is broad.

What it means →

The canonical umbrella tag for omegaverse, a fanfiction-original genre assigning characters secondary sexes (alpha, beta, omega) with biological hierarchies, heats, and bonding. Born in the early 2010s, it has grown into one of fandom's most distinctive worldbuilding traditions and even influenced commercial romance publishing.

What it means →

A canonical tag for works with aromantic characters or aro themes, exploring lives where romantic attraction is absent and other bonds carry the emotional weight. It anchors a corner of fandom devoted to stories that de-center romance entirely.

What it means →

A canonical tag identifying that a character in the work is asexual, whether canonically established or interpreted by the author. Ace fans use it to find representation, and fandom headcanon has built thriving ace readings of characters across many canons.

What it means →

A canonical tag for works engaging with asexuality as subject matter: discovery, explanation to partners, or life lived ace. It marks thematic focus where Asexual Character marks presence.

What it means →

A canonical tag covering the wider ace spectrum, including gray-asexuality and demisexuality, for works whose characters fall somewhere along it rather than at a single point. It reflects fandom's adoption of increasingly precise identity vocabulary.

What it means →

A canonical tag marking a bisexual character in the work, whether canon-confirmed or headcanoned by the author. It is among the most-used identity tags on AO3, reflecting fandom's enthusiasm for bi readings of canonically ambiguous characters.

What it means →

A canonical tag specifying a bisexual woman in the work, used both for canon bi women and for fandom's many bi readings of female characters. It serves readers seeking f/f and f/m stories anchored in explicitly bi identity.

What it means →

A canonical tag specifying a bisexual man in the work, addressing the particular scarcity of bi male representation in mainstream media. Fandom fills that gap prolifically, and this tag is where the filling is filed.

What it means →

A canonical tag for works thematically engaged with bisexuality: realization arcs, biphobia confronted, or the texture of bi experience. It signals the orientation is examined, not just present.

What it means →

A physicality tag covering bites in heated contexts — playful nips, claiming bites in creature fandoms, and vampire or werewolf mechanics where teeth mean transformation or bond. Intensity ranges from affectionate to explicitly sexual depending on rating.

What it means →

A position tag used in explicit Drarry works to indicate Draco takes the receptive role in sexual encounters. Readers in large slash fandoms often filter by these tags to match their established preferences, which is why authors label positions explicitly.

What it means →

A soft-focus tag for M/M works where the point is simply two boys or men being sweetly, openly in love. It signals tone more than plot: tenderness, mutual adoration, and a story interested in joy rather than obstacles.

What it means →

The softest entry in the kissing tag family: quick, affectionate pecks on the cheek that can be platonic, familial, or the first brave step of a crush. In pining fics a single cheek kiss often carries an entire chapter of emotional weight.

What it means →

A freeform warning tag for a trans character being called by their former name, a specific harm given its own tag because of its weight. It appears in transition narratives, hostile-family storylines, and identity-reveal plots.

What it means →

A canonical tag for works featuring demisexual characters, who experience sexual attraction only after deep emotional bonds form. Fandom finds the orientation narratively rich, since it makes slow-burn structure an identity rather than just a pacing choice.

What it means →

A tag asserting that all sexual content in the work features clear, eager, affirmative consent from everyone involved. Authors use it both as reader reassurance and as a deliberate craft choice, writing check-ins and verbal consent as part of the intimacy rather than interruptions to it.

What it means →

The umbrella term for fanworks centering romantic or sexual relationships between women, the F/F counterpart to slash. As a tag it flags works within femslash fandom culture, including events like Femslash February that exist to boost chronically under-written F/F pairings.

What it means →

The dizzy, formless experience of liking someone for the very first time, usually in childhood or adolescence settings. Authors use it for origin-story romance — childhood friends fics where the crush never quite went away — and for queer awakening narratives.

What it means →

A canonical tag identifying a gay character, applied to canon representation and authorial interpretation alike. In fandoms where subtext outruns text, the tag marks works that make the reading explicit.

What it means →

A canonical tag warning that a character's dysphoria is depicted: the distress of misalignment between body or perception and gender. Trans authors write it both as catharsis and as honesty, and tag it so trans readers can choose their moment.

What it means →

A canonical tag for works thematically exploring gender itself: questioning, transition, presentation, or the gap between assigned and actual. It marks gender as the story's subject rather than a character attribute.

What it means →

A canonical tag for characters whose gender shifts over time, covering realistic genderfluid identity and fantastical embodiments like shapeshifters whose fluidity is literal. Mythological tricksters in modern fandoms have made it a notably busy tag.

What it means →

Kisses pressed to knuckles, palms, or wrists — a courtly gesture fandom adores for period pieces, royalty AUs, and characters too reverent to aim higher. The hand kiss reads as devotion and restraint at once, which is why slow burn writers love it.

What it means →

A tag for the marks left behind by enthusiastic kissing, and more importantly for the morning-after comedy of trying to hide them. The hickey is fandom's favorite incriminating evidence, outing secret relationships to observant friends one collar-tug at a time.

What it means →

A canonical tag for intersex characters, used in realistic representation contexts and, separately, in some omegaverse and creature settings with non-standard biology. The realistic strand is small but valued; the tag's two uses are usually easy to tell apart from companion tags.

What it means →

A tag for the deliberate intimacy of one character settling into another's lap, whether from limited seating, boldness, or established-couple comfort. It is a favorite escalation beat: casual enough to be deniable, close enough that nobody believes the denial.

What it means →

A canonical tag marking a lesbian character in the work, central to femslash fandom's tagging practice. It helps readers find stories where a woman's identity is named rather than left to implication.

What it means →

A canonical umbrella tag for works substantively engaged with queer experience, beyond simply featuring queer characters. Identity, community, prejudice, and pride as subject matter all fall under it.

What it means →

A canonical tag specifying that a character's first sexual experience occurs in the work, narrower than First Time's first-together meaning. Stories under it typically dwell on inexperience and the care taken by a partner.

What it means →

Close cousin to the hickeys tag, covering gentle biting and marking during kissing or sex as an expression of passion or claim. In creature fandoms it shades into vampire and werewolf territory, where a love bite can carry literal supernatural meaning.

What it means →

Infatuation written as a physical condition: appetite gone, focus shattered, heart palpitations at a glance. The tag covers both the figurative mooning of a hopeless crush and literal magical or hanahaki-adjacent ailments where love manifests as illness.

What it means →

One character working knots out of another's shoulders, a setup fandom uses as plausible-deniability touching that neither party can quite call innocent. It appears in masseuse AUs, post-fight care scenes, and countless 'this means nothing' moments that mean everything.

What it means →

A canonical tag warning that a character is referred to by the wrong gender, whether maliciously, ignorantly, or pre-realization in the narrative's own voice. It is tagged with care because the experience lands hard for many trans readers.

What it means →

A physical-affection tag for kisses pressed to the throat and neck, a charged gesture that sits between sweet and heated. Authors tag it both in soft established-relationship scenes and as the tipping point where making out turns serious.

What it means →

A canonical tag for characters outside the gender binary, applied to canon enbies, headcanoned ones, and original characters. Fandom also uses it for canonically agender beings (robots, aliens, deities) given thoughtful nonbinary framing.

What it means →

A canonical tag for pansexual characters, an identity fandom often assigns to charming, flirt-with-anyone canon figures and to characters in settings where gender itself is fluid. The tag's growth tracks the term's rise in broader queer vocabulary.

What it means →

Couples being openly affectionate where others can see — hand-holding, kisses, and casual touches in front of friends, press, or scandalized teammates. Authors use PDA for soft visibility, possessive statements, or the comedy of onlookers' reactions.

What it means →

A canonical tag promising that the long-simmering tension finally breaks within this work, often written specifically to resolve what canon or a previous fic left hanging. It is the payoff tag of the UST economy.

What it means →

A tag for deliberate, strategic romantic or sexual pursuit — one character setting out to win another with charm as the weapon of choice. It powers spy fic honeypot plots, courtesan AUs, and comedies where the seducer catastrophically catches feelings.

What it means →

A canonical tag for works containing sex at unspecified explicitness, commonly paired with Mature ratings where the content is present but not graphically rendered. It is the middle band between implied and explicit.

What it means →

The comedic-agonizing state of wanting someone unbearably and being unable to act on it — through circumstance, denial, mutual obliviousness, or sheer cosmic interruption. Authors mine it for slow burn fuel and for farces where the universe blocks every attempt at privacy.

What it means →

A canonical tag for the turbulent realization phase: a character discovering their attraction does not match what they assumed about themselves. Fandom writes it constantly, often comedically ('he's very straight, except for him') and often tenderly.

What it means →

A canonical tag intensifying the plain Smut label with cheerful self-awareness: the author wrote explicit content on purpose and offers no narrative alibi. The 'shameless' is a wink at old apologetic posting habits fandom has outgrown.

What it means →

Fandom's oldest pairing term, born from the '/' in Kirk/Spock, denoting romantic or sexual relationships between men. As a tag it identifies M/M-focused works and connects to decades of slash fandom history predating AO3 itself.

What it means →

The canonical umbrella tag for transgender characters of any gender, covering canon trans representation and the vast tradition of trans headcanons. Trans authors have built substantial bodies of work under it, writing the representation mainstream media rations.

What it means →

A canonical tag specifying a trans woman or trans feminine character, marking both canon representation and fandom's trans-feminine readings of beloved characters. It gives trans women readers a direct route to stories that include them.

What it means →

A canonical tag specifying a trans man or trans masculine character in the work. Trans male headcanons of popular characters are among fandom's most developed representation traditions, much of it written by trans men themselves.

What it means →

A canonical warning tag for depicted anti-trans prejudice, including rejection, misgendering, and violence. Trans authors who write it for catharsis or realism tag it diligently so trans readers are never blindsided.
