Super Street Fighter 2 HD Remix on Xbox Live.
I've been playing Street Fighter since 1992. I went online to pit my skill against the rest of the world and wound up joining a group of about 4 other guys. They each took turns raping my best characters and making fun of my "skills" while they did it. Poor Chun Li. To this day, when I select her, she gives me this "please don't do this to me again" look.
Apparently, I suck.
