game squeakers
little kids, usually 10 or younger, who play call of duty or halo 3 and think its a big deal that its rated M. They typically have high-pitched voices that make you want to harm yourself, and think they're awesome at every aspect of the game they play. Usually (often in the case of call of duty) if your whole team is made of game squeakers they all try to snipe and your team ends up loosing by 900 points or more.
So i was playing Halo 3 yesterday and these game squeakers all had full hayabusa armor on, wouldn't shut up, and accidentally sniped me six times.
