G B C 

G.B.C.- Glorified booty call,is when someone is someone's steady fuck buddy,but really does not care, or love them as much as they act. Generally a semi- girlfriend,or semi-boyfriend who is fucking you just because they can,and maybe they like you just a little bit too.

" Man, I wish I was more than a G B C to my semi- Boy-friend.

Greasy Beefy Curtains. When the lips of a woman's vagina appear stretched out and hanging like a curtain, brown in color like a piece of beef, and shiny like grease.

The stripper's face was hot, but one look at her G.B.C. and I was running for the hills.

Anti-Gravity Ball Sack Capacitor. IE: The feeling you get when something made you extremely happy, similar to when you are on a rollercoaster ride and your balls float up and feel neat.
