Crowd booing has long been a staple reaction in fighting games, where arena audiences turn on a fighter after a poor showing, and this clip is shared on soundboards under a Tekken tag.

Its appeal is its clarity, everyone recognises booing instantly across languages, so it keeps circulating as a simple, universal way to signal collective disapproval online.
