Fluff — Tag Meaning
Fluff is AO3's catch-all label for sweet, low-stakes content designed to make readers feel warm rather than wrecked. Authors apply it when the heart of the fic is affection — characters being soft with each other, gentle humor, cozy moments — with conflict either absent or trivially resolved. It is one of the most-used freeform tags on the entire archive.
What to Expect From "Fluff" Fics
Comfort reading with minimal tension: expect smiles, tenderness, and an ending that leaves everyone okay. Word counts skew short, though long fluffy fics absolutely exist.

Tooth-Rotting Fluff
An intensifier on regular Fluff — the name jokes that the story is so sugary it will rot your teeth. Writers reach for this tag when they have deliberately maximized cuteness and stripped out anything resembling real conflict, often as a palate cleanser after heavy canon events or angsty fic binges.

Domestic Fluff
Fluff set in the rhythms of everyday home life: cooking breakfast, arguing over paint colors, falling asleep on the couch. The tag is especially beloved in fandoms where canon never gives characters a quiet life, letting authors imagine spies, superheroes, or soldiers doing laundry together instead.

Fluff and Angst
Signals a fic that swings between sweetness and pain rather than committing to one register. Authors use it for stories where tender moments and emotional gut-punches are deliberately interleaved — the fluff makes the angst land harder, and vice versa. It makes no promise about which mood wins in the end.

Happy Ending
A reader-service tag that spoils exactly one thing: everything turns out okay. It is most valuable on angsty, dark, or high-stakes fic, where it functions as a safety rail letting readers endure the middle knowing the destination. Many readers filter by this tag exclusively.
