The act of slapping someone on the back or on any other part of the body, with your hand in a cupped manner, and creating an air pocket in your hand, so it creates a loud noise.
To be boned in the ass like a badukusaurus (a gay, pot smoking, tutu-wearing, satchel bearing, nail-polished unicorn dinosaur who has a goatee and a heart tatoo on his shoulder)
Josh, don't you just love getting badukued by Kevin?
