The Crust Thrust 

This is when you keep a pair of your unwashed Boxer's (This is the Ideal choice) for a whole week and on the weekend you find a girl bring her home, now you start doing it doggy style and when your ready to finish you garb your boxers put them over her head for the Final thrust. thus you have completed The Crust Thrust!
