MFS

Minimal Fuckability Standard -- Differs among everyone. But where a man (or a woman) guages the other sex's attributes in question of whether they would or would not fuck them. Some have lower stands, and others higher. Looks, jobs, and more importantly, alcohol factor in.

Woman: Oh, has a giant mole on his cheek. I don't think he reaches my MFS.

Woman #2: But he drives a Mercedes, I think I will fuck him tonight.
