Crack — Tag Meaning
Fic powered by an absurd premise embraced without apology — characters turned into cats, gods forced to share an apartment, a sentient toaster's perspective on the plot. The name comes from the old joke that the author must have been on something. Logic is optional; commitment to the bit is mandatory.
What to Expect From "Crack" Fics
Deliberate absurdity played for laughs, with canon physics and characterization bent as needed. Don't look for sense; that's the point.

Crack Treated Seriously
Takes a premise that should be a joke and writes it with complete sincerity — full characterization, real emotional stakes, careful worldbuilding around something ridiculous. The tension between absurd setup and earnest execution produces some of fandom's most surprisingly moving work.

Humor
The umbrella tag for fic that wants to make you laugh, spanning witty banter, situational comedy, farce, and gentle absurdity. Unlike Crack, Humor implies the story still operates within recognizable canon logic — it's funny, not unhinged.

Parody
Comedy that imitates to mock — skewering the source material's clichés, fandom's own tropes, or another genre's conventions. A parody fic might rewrite canon in the style of a soap opera or lovingly roast the fandom's hundred identical coffee shop AUs.

Shenanigans
A cheerful catch-all for mischief, capers, and lighthearted chaos — heists that go sideways, group schemes, escalating pranks. The tag signals ensemble energy and a story where the fun is in watching characters cause and survive nonsense together.
