Guy 1: "Dude! Did you see this hot chic on Facebook?"
Guy 2: "Yeah, but look at the angle of her profile pic. I think she has a ninja chin."

brain ninja

Title given to girls by comedian Dane Cook. Girls have the power to fuck with a guy's mind by saying something so simple that it eventually drives them crazy.

Girls are brain ninjas! They know how to get in there with their katanas and cut ya! And then disappear into the night!
