What is Frusting?
1.
Frusting is the act of saving frust(dead skin foot particles)and storing them in a contatiner. Frusting happens when a male and female are having sex. As the male is going at it he secretly grabs a hand full of frust. At the moment of male climax he pulls out and busts a load on the females face and at the same time he whips the hand full of frust upon her gooey face. (Can also be used as frusted)
Shelp planned on Frusting that hoe but wasn't in on it by himself. As he busted on her face Shelp's buddy ran in the room and tossed frust in her face as he yelled "Frusty" and then ran out of the room.
