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!

f-u

Possibly the worst finisher in pro wrestling history, done by none other than john cena. You want to know what an f-u feels like? Do a somersault on your bed. That probably hurts more than the fucking f-u.

The f-u, one of the most "devastating finishers" WWE has to offer.
