Have you ever pooped your pants as an adult?

Only once. I took an enema, and I felt that sensation of farting, but when I did, I pooped myself.

Do you mean a full on load or just like a shart?

yes going to a doctor's appointment in an lift bus and the driver was taking his time and I told him that I didn't feel well and then filled my panties and his seat with my shit

Multiple Times.

No.

On the way home from being out one night, the combination of alcohol and a big, filling burger did a number on my stomach. Thought I could make it home, however..At a red light..Let a load loose in my pants that made such a mess that, when I got home, I just tossed my jeans and boxers into a trash bag, washed myself off with a wet dish towel, tossed that into the bag, too, tied it, and threw it into the trash can. Would have taken an industrial-strength washing to get my clothes cleaned after that massive, dino-shit.

Does sharting yourself count?
