look up any word, like bitch stare:
An over priced old rock that gets you laid until the effect wears off. Bigger is better.

1) The hardest natural occuring form of the 6th element of the Periodic Table (Carbon). When cut properly it can appear to be very brilliant due its refractive index.
2) A playing field, in the shape of a square, where the corners are bases. Used to play baseball and variations of baseball, like T-Ball, softball, and kickball.
3) A 2D geometric shape with 4 sides of equal length, but with differing perpendicular angles. Actually a rhombus, but commonly called a diamond when a corner instead of a side is at the bottom.
1) It sparkled like diamonds.
2) Let's go to the diamond.
3) Draw a diamond.

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?

n. Relatively common mineral, consisting of carbon, which is similar in appearance to zircon or cut glass. Used by the South African based De Beers company as a form of emotional blackmail through clever, original, and socially planted marketing techniques. It is asserted by the De Beers company that a man who is unwilling to waste a huge amount of money for a worthless piece of carbon must not really love his future wife very much.
