B-on-B
Boob to Belly Ratio. It’s how big your chest is compared to your gut. Scientists are using mice because humans are too lazy to measure.
My B-on-B is 1 to 10. I look like a deflated balloon.
Her B-on-B is 10 to 1. She’s got a chest like a mountain.
That guy’s B-on-B is like 2 to 3. He’s got a gut like a pit.
