Double Up 

A Wakeboarding manuever in which the boat's driver navigates the boat back across its own previously created wake. The current wake and the wave created by the old wake come together to momentarily make one enormous wake, which the rider hits to achieve massive air. The path of the boat roughly approximates the letter P, starting at the bottom and crossing the wake heading left.

Bonifay's half-cab double backroll off the Double Up is the sickest move around...

double up 

When you are with a bunch of your friends and one of them makes an audible fart. At this time you or another one of your friends silent farts and then blame the smell on the friend whose fart was heard

Its a well known fact that when a guy farts, a girl will silent fart and double up on the guy so he gets the blame.
