Smiling Commando 

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

Smiling gunman 

Something you don't see often.

Your murderers might come to you with a smile, but most of the time they are not still wearing one at the time they kill you. A smiling gunman is rare.
