A very sexy, attractive girl that will initially draw you in by her eyes. A mosa is a girl who has the perfect combination of beauty and brains. Mosas are sexy even when they roll out of bed with no make up on or if they are just wearing workout pants. Their sexiness is second only to their thoughtfulness. A mosa is the best catch.
Wow, I cannot stop thinking about this girl. Everyday, something reminds me of her, and I long to be with her. She is definitely my mosa.

Used to describe a man who has bad luck with deserts. Said best by all around funny man Conan O'Brien.
"Mosas, this is God, go wash my car."
