Means "beloved" in Greek.
The best friend you will ever have. A beautiful, witty girl who drives an earth killer and is banned from consuming milkshake beverages. She owns enough handbags, blouses, and perfumes to start a Macy's. Also, your future maid-of-honor.
"Dude, who was that chick with the Coach sunglasses driving the really obnoxious truck?"
"Oh, that was just Carissa."
