mustanger 

In military slang, an officer who previously served as an enlisted soldier.

Best officers I encountered during my time in the service, bar none, were "mustangers" (former enlisted who became officers) and warrant officers. Most of the others (ROTC, OCS or West Pointers) were frag-fodder.

Mustaeen 

The literal definition of an asshole. Backstabs friends, takes hundreds of photos of them without their permission, and acts like he's the best at everything but everyone knows hes not. He will always talk about you with others, and share pictures despite the fact that the victim knows about it. Usually this person will make someone look bad so he seems cooler than them. He also likes to lure in girls to play minecraft so he can get coochie.

Man, that guy is such a Mustaeen, I wouldn't wanna be his friend.
