Like saying you're a girl on CoD is probably just going to get you thrashed.

You'd be surprised. Not so much now, since voice chat in public lobbies is nowhere near as common as it was, but people used to act out if they heard a female voice. I've seen some desperate attempts to get a girl's attention. There were some "kitchen" jokes, but I saw the opposite more often than not. That was up through the Advanced Warfare era.
