Copypasta

A repeated block of text posted en masse in Twitch chat to signal reaction, reference an inside joke, or overwhelm other chat. A core unit of Twitch chat culture.

A copypasta is a block of text — typically absurd, ironic, or referential — that users copy and paste repeatedly into Twitch chat to produce a coordinated reaction or overwhelm the flow. Copypastas are one of the core primitives of Twitch chat culture, functioning as in-group passwords, recurring bits, and real-time memes. Examples like the “Navy Seals copypasta” or the streamer-specific copypastas that emerge organically around inside jokes are among the most-quoted artifacts of the medium.
