The clip comes from Family Guy, the long-running animated sitcom built around Peter Griffin, the loud, impulsive father at the centre of the Griffin family. Short excerpts of Peter's voice have long been reused online because his delivery is instantly recognisable, even out of context. This particular line spread through soundboards and short-form video edits, where creators use it as a blunt, shocking punchline. Its continued use comes from that instant recognition: listeners know the character immediately, so the joke lands without any setup.
