Noun: Any woman who uses video game/nerd culture as a means of artificially increasing her rating on the hotness scale or to obtain undeserved attention from a male audience.
She may even play mainstream games such as Halo/Gears/CoD/etc but will generally have an over inflated sense of self. This is due to the fact that many in the video game community regard moderately attractive women who game thusly: "OmG!! G1rLs Wh0 G4mE ARE HAWT!!"
These types of women will continually point back at the fact that "I play games and menstruate, and therefore, you should worship me" by doing a variety of things. Such as cosplaying or larping as the sluttiest VG character they can find.
Posting images on their blog or tumblr of them naked with only 360 controllers or Mario plushies covering their naughty bits.
Getting a video game based "tramp stamp" or other risque vg based tattoo.
Playing a popular game in a bikini, lingerie, or form fitting clothing (that may or may not contain imagery that's part of video game/geek culture). Then taking pictures of it. Then posting said pictures on the web.
If you spend more time telling people that "you're a girl who plays games" instead of "here's the games I play" you may be a faux gamer girl.
