Get the Bro-Up mug.
A really hott girl that knows things about games, the internet, and music. This girl can chill with the guys and not seem out of place at all. She doesn't bitch about nonsense and is totally down with dirty jokes and poking fun. This girl looks like a total babe and acts like a total bro. Girls of this sort are difficult to spot with the naked eye, unless they give a clue like a cool retro t-shirt or some internet lingo. If you find one, capture it.
"dude your girlfriend is a TOTAL bro-up doll"
"dude i know, she kicked my ass at halo last night"
"where can i find one!!"
