"Ballin" 

THIS IS THE OFFICIAL, ORIGINAL DEFINITION. EVERYONE SAYING OTHER THINGS ARE MISINFORMED.

A woman is said to be "ballin" when she is secretly carrying cocaine in her vagina. The term arose in the 80s, when Cocaine was most prevalent in the US. The term has gradually shifted into another word for "cool" though.

Hey guys, that chick is "Ballin".
