I just played some Halo 3 and I think I had my best game ever. It was a ranked team slayer game, and one team member quit before the match started. So there was three of us versus four of them, and I OWNED with 21 kills, dominating the match. The match was a nice mix of ghost splattering, sniping, and melee. I felt good.
Then in the next match, it starts off on a level with a ghost. I got for it only to hear a guy behind me yell "DON'T YOU FUCKING TAKE MY GHOST YOU MOTHERFUCKER!!!!" But I got it before he did. He continues with "YOU FUCKER" and climbs into a warthog by himself. I turn around and start firing at him. "STOP IT YOU FUCKER!!", he retorts. So I go on my way and the guy is STILL insulting me, so I decide to have some fun and just team kill him. He's enraged and another guy, probably a friend of his, joins in with the same "STOP IT YOU MOTHER FUCKER!!!" ranting. Then he tries to kill me, so I splattered him and this got me kicked from the match. That was the first time I've ever team killed an annoying teenager in an online match in Halo 3, and it felt good.

So then I loaded up Mass Effect and keep getting my ass kicked at the save point I'm at.
Also DCharlie was playing SHADOWRUN for a while.

I thought that was shit?
