The weight to tit ratio relates the bra and pant size of a woman to their fuckability. It is derived from the concept that large breasted women are more likely to be fat asses than small breasted women. However, men are willing to take a small amount of fat if it means bigger tits, to an extent. The weight to tit ratio helps men decide if the tits are worth the fat. The exact definition is:

T/(W^2)=F

Where T=Tit Size, W=Weight, F=Fuckability.
