Fump 

Combination of 'fart' and 'dump.' A fump is when you think you have to take a big shit, but when you sit on the toilet to do it, you just let out a huge, explosive fart. Some small, misshapen pieces of poo usually accompany a fump.

"Man I thought I had to take a huge shit, but it was just a fump."
