"Tryhard"
- I play CoD (Black Ops) and when I win (I play free for all and have a 2.21 kill/death ratio) I am called a tryhard versus the asshat spinning around (trying to) shoot[ing] me with a sniper rifle.
I don't use "cheap" (another word I hate) guns either, you won't see me use the famas in Black Ops, I use various different guns depending on the map. FOR EXAMPLE I always use the Mac11 extended mags (scavenger, sleight of hand, ninja) on the map Nuketown.
"ur"
- I know it's an abbreviation but when using it people could at least use it properly, "ur" is an abbreviation of "you're" not "your".
"plz, pl0x"
- After seeing this in a chat box on whatever online game (I see it on Minecraft a lot) I am far more inclined to deny the person of whatever is they're requesting because they use those stupid, repulsive, abbreviations.
EDIT:
"camper"
- bringing up CoD again, I'm given this title over and over again

. I win the game by a certain difference, between myself and the player in second, and I just get this label slapped right on me. Camping, to me, is when you sit in a corner sights trained on a doorway with a proximity device covering any other methods of entrance; although I like it more it, just pissed me off how stupid it is, when people aim at the same spot they placed their proximity explosive device at, covering it as if they don't want it to explode (#morons)
