The name borrows the internet slang go brrr, used to describe something running fast and out of control, and applies it to a single exaggerated clap burst. The clip itself has no clear credited source and spread mainly through meme soundboards and short video edits, where short loud reaction sounds are reused as punctuation. Creators keep returning to it because the meaning is instant without any words, working as applause, mock praise or hype in under three seconds across gaming, reaction and comedy videos.
