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.

F-U
Current WWE champion John Cena's oh-so-intimidating finisher. An overglorified standing fireman's carry.
Typical announcer over-reaction:

OH MAH GAWD! It's the F-U! Cena picked him up on his shoulders, and dropped him to the ground! A lesser man would have died from such an attack!

fu
Short for "fur", as a horrible insult to say to one person (and only one person). When "fu" is said to someone, it means you hope someone has an allergic reaction to fur.
Person A: "You're a lose-r"
Berson B: "fu!"
