Muteen 

When you say you are going to show up at school, but end up watching TV-series and shutdown your mobilephone instead.

Mustenance 

A cake like substance or smell, or any combination of the two, that exudes negative vibes.

That weird brownish black shit that gets all caked onto your computer mouse or video game controller, that's the mustenance.

I left my dinner out over night and as a result my sustenance developed some mustenance.

The film that develops on the toilet seat of a public restroom is mustenant of a neglected cleaning.

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.
