I'm temporarily living in this house/hostel crossover and 4 of my housemates play Call of Duty. A lot (it's brutal ). Now I've always heard rumours of the swearing kids in this game, but never knew anyone who actually plays like that. Until a couple days ago when suddenly I heard loud German swearing coming out of the living room. It was my housemate playing Black Ops, and he has been playing like the rumoured swearing kid ever since that fateful day.

What are your examples of witnessing gamer stereotypes in the flesh?
