Hahahaha, okay, storytime:
Had an epic moment like that while playing Combined Arms on Skyshock last weekend. I was the top player on my team, and the top player on the opposing team did a teabag after he shotgun charged me for the second time in a row after I was already damaged from killing one of his teammates literally a second or so before.
I got pissed off, next time I saw him, I double-tapped him with my Super Pox VLO, then teabagged him. He went immediately back to where I was, and lucky son of a bitch, arrived and shotgun charged just as I finished killing a teammate one on one AGAIN.
This precipitated a crack in my usually calm Crucible demeanor and I got pissed. I'm in the top 2% of players with a KDR north of 2.0 as well, so if you do manage to get me completely fucked off at you with your poor sportsmanship, odds are I'm going to be able to deliver on the revenge. I made this teabagging fool Target #1 and started purposely watching for him on the field.
Game over right on time. Teabagger immediately quits despite having the highest score over me by a small margin. Mission: Accomplished.
