Cupcake Butt Muffin 

During sexual activity, this is when one person shits in a paper muffin cup and someone else cums on it. They both eat the delicious baked good together. Sometimes, if it is the right time of the month, the woman may add some of her menstrual blood to make a pinkish frosting, mixed with the man's ejaculatory juices. It is also likely that the fresh poop will be hard to eat, so it is common for the muffin to be cooled in the refrigerator so it can harden a little. No one has ever actually tried to bake this concoction before, and it is not suggested to do so.

Man: I am hungry, would you like to bake some brownies, honey?
Woman: How about some cupcakes instead?
Man: Only if they're Cupcake Butt Muffins!
