look up any word, like bukkake:
 
1.
A cool new hairstyle that is all the rage in which both the left and right halves of one's hair flip out in the same direction. A small segment of the population are lucky enough to be born with hair that is naturally inclined to position itself in such a sexy and trendsetting way, while others must spend hours standing perpendicular to a fan to create the look.
"Wow, that girl over there has an Under and Out - if only I was cool enough to pull off that hairstyle."

Or

"I went to my stylist yesterday and asked for the Under and Out - she said she hadn't heard of it and I said she should have her style licence revoked!"
