FU 

1)Shorthand for "F*** You" if you can't say the actual words without getting into some kind of trouble, ie school, work, parents, etc.

2)Appropriately named finishing move of young WWE wrestler John Cena. Its the modified copy version of fellow wrestler's Brock Lesnar's F5 finishing move. You kick someone low like in the stomach or balls and pick them up over your shoulders then slam them to the ground from your side.

Ex1-Student 1: Ha-ha! You failed the test!
Student 2: Man shut up! FU!

Ex2-John Cena gets the pin on JBL with the FU.
