Lurk is a character from Kids A-Z, and this line comes from a scene where his argument with Bonk boils over into a full shouted outburst. The clip lasts only about a second and a half, which helped it spread as a quick reaction sound online rather than a longer meme format. Its popularity comes from how clearly the emotion reads without any context, allowing editors to reuse the anger for games, group chats, arguments and everyday frustrations in short videos and soundboard posts shared between friends.
