You have bottomed out when you sit down in a port-a john and the mound of shit and paper is so high that your ass and sometimes your junk touches the top of the pile. This usually happens during high risk activities like sitting on the seat of a port-a-john in the dark.
I had to shit so bad that I didn't look in the hole before sitting down-I bottomed out! I knew it was a going to be a bad day when I felt that mushy mound of shit connect with my ass hole and balls!
