When a chick brings it upon herself to wear a very short skirt and no under in public. Often sitting down and flashing her vertical smile to everyone who just happen to glance and smile back.
Guy 1: Dude look at that over there. That bitch over there is totally giving me a smiling commando.
Guy 2: She should've put on some damn underwear. Whore.
Guy 1: Thank God she didn't :D
