Cake with frosting

Its when you ejaculate on a womans buttocks and slather the seminal fluids across the buttocks and start biting at her buttocks and proceed to shout "I'm eating cake with frosting!"

John: Hey did you hear what paul did the other night?

Chris: Yeah! I heard he had some cake with frosting since the wife allowed it!

John: Man, I'm jealous!

Chris:Yeah, me too.
