<Snipped quote by Sol Grim>
It's an insult so called 'pro gamers' use against those who don't play many games.
Other way around. Its a an insult that pro gamers use for people who play MANY games. So you doint JUST play COD, but you play Batllefeild, CSGO, Killzone, and other games. You play all mannor of games becase you find them fun, not becase you like the game itself and want to "Pwn sick n00bs"
