Someone who always finds a way to lose a winning situation. You can be up by infinite points, and the choker will always find a way to blow it. You never want one on your team.
Yingy is such a chokeaholic. We were about to beat the level, until the chokeaholic blew it. * I'm using the name Yingy because I was just on a multiplayer game and Yingy was the big chokeaholic.
