carbonate

When you sit on the toilet to take a dump but you only end up farting a bunch of times.

"I hope you had a good shit cause we still have a while to go on this road trip."
"Um. Well, it was kinda frustrating cause I guess I didn't have to go that toilet"
"Son of a bitch!"
"Hey, it's not my fault I was only able to carbonate that toilet! I really thought I had to do go!"
