The beauty rating of your date or partner during a night of a partying. She/he is quite ugly normally, but attractive and hot after a night of drinking. (Source is from a good country song).
"After about three drinks at the party, I came to the conclusion that she was a 2 at 10, and 10 at 2."

Used to describe something you consider to be amazing, but really probably isn't. Subsequently used by those around you to make fun of you.

10 out of 10? Really? That rating is reserved for like, Lord of the Rings!
