Coach Buzzcut is the gruff teacher from the MTV animated series Beavis and Butt-Head, known for shouting health and gym lessons at the two teenagers. This line, in which he announces a lesson on venereal disease, became a favourite on meme soundboards because its blunt delivery turns a serious school topic into comedy. Creators reuse it for sex-ed jokes, awkward classroom edits and reaction videos, where Buzzcut's authority makes an ordinary warning feel hilariously overblown. Its short length also makes it easy to drop into TikTok and YouTube edits.
