A guy who can't get a girl because all of them decide to claim him as a best friend. Every chick claims he's attractive, but every chick says there is someone out there for him. Probably not though.
Girl: This is my best friend Kell
Kell: Well I wanted to get on, but I'm obviously a diamond.

A guy who ditches all his friends to fall in love with the first girl he sees. In most cases you will go months at a time without seeing him, but he will make facebook appearences stating his dying love for this girl. Every 4 minutes.
Ya, Thad saw that girl at the party, she was hefty and he's still being a Diamond.

Did you see Eric's post on facebook, I was hoping it wasnt so but we wont be seeing much of that Diamond anymore.

You think that chick turned Roy into a Diamond?
