A cake that is baked for people you are "friendly" with but you actually cant stand them. So when they invite you over, you say to them yes ill bring cake from dessert. You then gut the cake and drop a huge shit in the middle of it. When they cut the cake and realize what is in it you act surprised and blame it on the most helpless cake store you can fine putting them out of business.
a cake with poo in it.

Example : " Honey im not going to their house for dinner unless we bake the poopiest poopiecake for them because they annoy me so much."
