450 splash

Wrestling move that can only be performed from the top rope in wich a wrestler flips forward in such a way, that his body describes a 450 degree angle only to land over his opponent (splashing him).

Paul London and Jeff Hardy do incredible 450 splashes.

The 450 splash must be seen to fully understand it (words don't do it justice).

450'd me 

He blind-sided me or took me down for no reason. The phrase is in reference to the Seinfeld episode in which Kramer buys the Commando 450 shower head to replace the low-flow shower head in his appartment.

Kid 1: (talking to girl) You know I play guitar...
Kid2: Yeah, to make up for your small genetalia!
(Later)
Kid 1: (to Kid 2) Dude, you kind of 450'd me back there!
