DoubleJump 

Quietly sneaking out a fart while people are smelling the stink bomb someone else just dropped.

The guy next to you in an elevator farts and everyone knows he did it. Right then you let out a silent but deadly one that makes everyone think that they are still smelling the first guys fart and that it just got a lot worse but really you just DoubleJumped him!
