I'm terrible at Street Fighter, but I still keep up most of the time and eventually I tend to get better as I keep playing. I can't stand losing, so I often like to play against one person until I manage to pull off a win. The same thing happens with Black Ops in regards to winning matches and boy, do I ever lose my shit over that game. It's weird because I'm pretty calm until things don't go according to plan, so once my K/D goes under 1.0, bam, I curse a shitload with every death. After a while I become self-aware of how ridiculous I'm acting over a video game and start cursing at that! I'd curse after dying then tell myself to shut the fuck up about it, making it more ridiculous.
Lucky for everyone else, I don't play with my mic plugged in when I'm alone and a lot more calm with friends, even though it probably doesn't seem that way with them.
