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.

Mustayeen

The greatest person ever. Makes everybody drool (guys and girls alike), but is determined to stay an eternal virgin. He is vulnerable to STDs due to his micro-penis

Friend: "Yooo look at that absolute sex magnet!"
Other Friend: "That's the holy Mustayeen bro"
