I have no clue about this either. The cup cake may have slipped by the feces that were trapped in your colon. I had this problem before, it's called being impacted. That's when there's so much stool backed up in there, that only mushy and watery substances can get by. You might need to get cleared out. I had to do six enemas and a bottle of mag citrate one night to clean out my colon. And I still had some in there. I was on the pot all night. But sometimes, I do get small pencil thin stool that comes out everytime I pee. Sometimes this is when the constipation is just trying to work it's way out! HTH. I'm going home now, I'll try to get back on later this evening!
