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).

Get the 450 splash mug.
When a man is about to climax, he pulls out, climbs onto the top rope, performs a 450 splash into the gash and busts a nut.
When John was about to cum, he pulled out of Anna, climbed to the top rope, did a gnarly 450 splash right into her. Only bad thing is that his condom flew off during rotation and now shes pregnant.
