My memorable live moment was Halo2.
Back then i always played with 15 of the same people, we were always playing. Over time there was a lot of infighting to the point where we formed sub parties and whatnot. Well, one day, the arogant guys (the ones who modded, bridged, standbyed, talked shit but werent good, im sure you know the kind). Well they formed a clan, using an annoying acronym (i forget it). But 4 of us who didnt join, called them out on it. So we had a 4 v4 (they were MLG fanatics so made it mlg rules), except we played to 100. SO we didnt try at first, it was like 20-50, and we were fucking around and they were serious. SO FINALLY we tied it 60-60 (yeah, we were that good :D) so this is what went down
ME: "Yoda, throw a grenade in there YOU STUCK ME!"
YODA: *laughing hysterically*
BILL: What did he do *betrayed by me*
ME: He did that
BILL: god damnt it!
Yoda: *had rockets and killed EVERYONE* hey....look what i did
Ill never forget that
