Bumblast 

The notion of Bumblasting is dipping your ass on to someone's face as a show of mockery or irritance.

The perception is in relation to "Tea Bagging" where as instead your aim is for your bottom (or a character in a video game) to connect to a body's face whether up or down from the floor.
