when you hold down the trigger of a shotgun and pump it, the gun will fire as soon as the pump reaches the forward position. not recommended because it puts lots of stress on the gun.

After getting the oppurtunity to put your dong in someone else's butt, you begin. After insertion, carefully begin to pee into the butt, waiting for the time when the reciever begins to turn around. At that point, give him or her a backhand as only roger federer can give, showing your reciever who's the real roger federer, and that he or she most definetly cannot fuck with you again

Mike : Damn, man, she's gotta be chafed after that.
