The name combines the Finnish word for song, laulu, with crude slang that gives the clip its cheeky, schoolyard humour. Little is documented about who first recorded this version, which carries a voice changer credit in its file tags, but its appeal online is easy to explain. Short altered voice clips spread well on soundboards and in edits because they are instantly reusable, need no context in another language to sound funny, and can be dropped into almost any video as a brief, absurd interruption that viewers remember.
