I poop when i laugh

Poo wen you need to don't hold it

You need to invest in some reverse-laxatives, my friend.

Stop havinganal sex; you could be loose.

It's never happened to me so I don't know how normal it is but I do know that laughing hard can do things to your abdominal muscles and relax the muscles in your asshole letting some poop come out. Basically it's normal.
