1. To do something so rediculously stupid and uncalled for that everyone yells at you and you flip out on them.
2. When everyone in the room goes quiet because you said a very stupid joke and no one laughed. The fact that you are a loser dosen't help either.
1. John pulled a winty after he let his friends shoot him with their paintball guns and then got angry and attacked them when they stopped.
2. John said a remark on the goof walking past him, and every one looked at him, it got quiet, and then everyone broke into simultanious laghter at John.
