Bad/Brian Girlfriend
When a guy starts dating in high school and his first girlfriend is one of the following: ugly, unattractive, overly tall, annoyingly loud, crazy, pathological liar, purple colored, or grinds like a whore.
When the guy breaks up and levels up to a normal girlfriend, the ex is referred to as his BG.
Ay mayne glad to see you finally got rid yo bitch. She was a real fugly ass pot bellied cerebrally chalenged BG.
