OT3 — Tag Meaning
Short for 'One True Threesome' — fandom's riff on OTP for fans whose ideal ship has three people in it. The tag marks fics where a specific trio is the romantic unit, often resolving canon love triangles by the simple expedient of everyone dating everyone.
What to Expect From "OT3" Fics
A committed three-person relationship as the emotional core, with the triad's internal geometry — who softens whom — as the draw.

Polyamory
Tags relationships among more than two people, written as ethical and consensual rather than as infidelity or a phase. Fanfic is one of the richest archives of polyamorous storytelling anywhere, using the tag for everything from established triads to careful negotiations of opening a relationship.

Love Triangles
The canonical tag for three-way romantic competition: one character torn between two, or two rivals pursuing the same heart. Fanfic both plays triangles straight and subverts them — a striking share of tagged love triangles resolve by the three becoming a throuple instead.

Established Relationship
Skips the courtship entirely: the couple is already together when the fic begins. Authors use it to explore what comes after getting together — domesticity, conflict, growth, or simply love in operation — territory canon and getting-together fics rarely cover. It is among the archive's most-used relationship tags.

Getting Together
The tag for fics whose story is the getting-together — the realization, the confession, the first kiss, the agreement that this is real. It is the bread and butter of shipfic: however the fic is dressed, its destination is two characters finally becoming a couple.
