Backstory: Playing on X-Box Live with some friends (in the same room as well), doing some Versus in Left 4 Dead. Now, I don't mean to sound cocky, but I'm damn good at the game. I don't boast to people online, I just put them in their place with a well thought out hunter pounce if they're being arrogant asses. This guy was, insulting me through private messages because me and my buddies were doing better than his team, so after the first game ended and we all went back to the lobby, he just started bitching about how we were obviously cheating. So, I challenged him to a one on one match (which, for those who don't know since it isn't a common thing in Left 4 Dead, means that one person on each team, and the survivor kills off the AI before they leave the safe area and you see how far you can get.) The map was Death Toll, and I played survivor first. Long story short, I made it through the first level in near record time, because this guy just did not understand the element of stealth. When his turn came, I got him with the first hunter I got. He immediately disconnected. Anyway, a few minutes later, he PMs me with the following message.
Douche on X-Box live: Dude, you obviously were cheating. All of my pounces just phased through you, you lag-switching douchebag.
Me: Why don't you just shut it and go crawl into a corner somewhere?
Douche: Why don't you go suck a cock like your mom? You should have been aborted.
Me: Yeah, well you're the load your mom should have swallowed.
He didn't respond after that. That's my favorite insult to use on X-Box Live when people annoy me, along with "the best of you dribbled down your mom's leg".
