Bonerdust (Boe-Nerr-Dust)

When you get done giving the 'ole bone to the beaver and you forget to wipe off the excess juices so they crusty and next time you get a boner, the crust snaps off and looks like dust
Kid: "Is someone in this room smoking?"
Me: "No, that's just my bonerdust from this morning... sorry bro!"
