Chocolate Chip Cake Frosting
After performing a copious amount of anal intercourse, prior to the moment of ejaculation, you pull out and slap it on the recipient's face. You spread the homemade buttercream frosting around. Because of the copious amounts of anal sex, the particles of poo stuck to your froster (penis) resemble a chocolate chip frosting.
