Guys who vary from short to average height, always very skinny/low in bodyweight. They tend to be verbally and physically very aggressive in order to compensate for their feeble figure, that of which they closely correlate with their self-worth. They slam their desks when playing video games, curse out their so-called friends, and basically rage at the slightest inconvenience in life. They're usually white, have almost never been beaten as a child, and have absolutely no respect for themselves or anybody else. It's basically the more severe version of napoleon syndrome.
Henry: Yo, I heard slamming and screaming noises the whole night and I'm was on the other side of the hall.

When someone is so skinny you can see their abs, despite them doing no physical excersise whatsoever. Usually caused by not eating enough.
