solid A 

A term you say when someone asks you how hot their friend is and you don't want to hurt their feelings. You don't say that he/she is a Solid 10, or a dime, because that is an actual way of rating the hotness of people.

Person 1: Hey, do you think my friend here is good looking? *motions towards friend*

Person 2: ... He's a solid A. No homo. *runs away from friend*
