I don't understand how people get off acting like this, period. I would always say "Sorry man" when I suck out like that, and in case of any excessive whining I will say "thanks coach". If they win, either say "nice hand" or keep mouth shut. The end. Running around like a moron while yelling at the top of your lungs after winning a 4:1 is for ignorant buffoons (been 10 years since I got to use this word I think), like the bowler guy with the headband.
