Basicallyanal sex...except for those that believe they are still chaste or "virgins" yet participating in anal sex.
All the BYU mormon students are having anal sex and call it "ChocolateFunnel Cakes" so that they still feel "worthy" and can still be "virgins" on their wedding night."
When a male defecates on a females chest and then follows this up with placing cum on top of said shit thus making a chocolate crap cake with cum frosting.
John: Hey dude, did you bang that girl last night?
Bob: Yeah and after she fell asleep I left a big Chocolate Cake with Frosting on her chest!
John: Oh man, that's gnarly, I feel bad for her.
If someone needs to pass on the chocolate cake, it means that they're a little hefty and need to lose a little weight. Could also imply pre-diabetic-ness.
A cake made of chocolate flavor. Its very yummy for most people, but the haters prefer vanilla. Chocolate Cake defines life, and why we live it. It also contains the reason why man was put on Earth.
