B2BR
How big a girl's boobs are compared to her whole body. If the number is high, she’s got huge tits and not much else.
My B2BR is 9000. I’m basically just two melons in a trench coat.
She walks in and the room stops. Her B2BR is like a math test I failed.
I asked her what her B2BR was. She said, 'I don’t know, but it’s probably higher than your GPA.'
