Almost like a rage quitter except they quit a game after only winning their first match. They usually quit because they know they are going to lose in a rematch, especially if they won by luck or some other circumstances such as bad internet connection. A win quitter is NOT someone who beats you fair and square and then gives you a rematch.
"We were playing a close game and he beat me with a cheap trick. I asked for a rematch but he refused. He's a win quitter."
