Finals Fifteen

Similar to the weight college freshman gain in their first year of college, but this is the 15 pounds everyone puts on during finals week. This can be credited to the amount of coffee and snacks consumed while staying up late studying.

Last night I stayed up until 3 A.M. studying for my biology final; I ate a whole box of Cheez-Its, two Little Debbies cream rolls, and four cups of coffee. Yeah, I am definitely going to gain the Finals Fifteen.

blackjack fifteen

Used to refer to a woman who isn't hot, but also isn't ugly. You aren't quite sure if you want to hit it.

Term is taken from the popular card game of Blackjack, where it can sometimes be difficult to decide if you want to "hit" when your cards add up to 15.

Bob: Oh man, look at her!
Larry: Eh...she's a blackjack fifteen.
Bob: No way. I would totally hit that.
