Can be referred to as BTR or BTTR ( I’ve heard it both ways )

Butt thigh ratio or butt to thigh ratio.

This is used when a person feels the need to express their lack of attraction to another person because the other person has huge thighs and a flat ass. Or their butt is perfection, But that have no support so you worry about the endurance of that ass
Bass got a nice ass.

Nahhh his thighs are too big. That’s not prime BTR , thank you , NEXTTTT!
