"I'm an online PC gamer."

I figured that...just trying to poke some fun at you- i don't know. I guess i hear it a lot from PC gamers, that they say i'm a loser because i play old nintendo games.

I'm sure there are lots of people who use the word 'pwned' and aren't flaming peoples who are doomed to be disgusting in your view, but they're likely PC gamers who are using a form of speech that are trying to have fun. (Though they're definition of fun might be different than everyone elses, and perhaps not in a self-perceived-as-disgusting type of fun either)
