This is when a woman shits in a paper muffin cup and her partner 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, and may result in the oven having to be replaced.
It may also be known as a butt
muffin, chocolate truffle, or butt cake.
Man 1: Me and
Sheila did some delicious baking last
night.
Man 2: Oh yeah, what'd you bake, some buttcake cup
muffins?
