Only by people I've played with online (I'm sure other gaymers would agree that this term is pretty commonly used in the online gaming community) although it's mostly because I kept hitting on this guy and saying pretty nasty things to him in PM so he throws that word at me in retaliation even though it doesn't work and I keep going.

(I don't hit on him anymore and we're still pretty good friends though we don't play much with each other anymore.)
In real life though, I don't think I've ever heard it. A huge part would be because English is only a second language here.
