Proshat
An extremely beautiful and intelligent female with a great sense of humour.

You'd be lucky to find a Proshat in your life because they are an irreplaceable friend.
Dude #1: Damn, you're such a great friend, what would I do without you?
Dude #2: I couldn't tell you, I guess I'm just a Proshat.
