Someone that when playing a game and loosing always suggest switching to some esoteric game that they only know the rules of.
"This game is nice, but I know a better game. Lets try to play (unknown game) instead. It's not hard, I'll explain the rules!"
"Come on, you do this every time you are loosing. Let's stick with the game we are playing. Don't be such a Sesh-head!"
