The sound is a short vocal outburst from Nick Carter's Get Over Me, featuring a shouted line by Avril Lavigne. Because it is so brief and direct, it travelled easily as a reaction clip, passed between meme pages and short-form video editors who needed a fast way to label someone as creepy without explaining the joke. Its appeal has lasted because the delivery is unmistakable even out of context, and the two-word insult fits almost any awkward encounter, from unwanted messages to uncomfortable stares in a crowd.
