The story behind the song:
"So my brother-in-law has a colostomy bag, which is basically your intestine sticking out from your abdomen where poop is discharged into a bag. He needs to change his bag once a week and obviously he can’t do it himself so I HELP him. It’s a bit painful, so I try to crack “shitty” jokes to keep his mind occupied as I change his bag. Well, he laughed a bit too much and poop just started to flow like a soft serve machine! Keep in mind he has no control nor can he feel it! He kept saying, “I don’t know how to make my shit stop!” This made both of us laugh EVEN MORE which created EVEN MORE poop! I had to wait until he was done before adding the new bag, so just when we thought that he was done, poop started to flow again except this time I asked him to take a picture! So attached is a picture of his open poop area in action!
In case you’re wondering why he has a colostomy bag, he was shot multiple times—nine to be exact—and one of the bullets damaged his large intestine. Although this is temporary, it’s the most uncomfortable thing to carry around. He also has to release the gas that accumulates throughout the day and when he does, WATCH OUT! STINK BOMB!"
