Bumsneeze

Often on the day after a hot curry or some food that didn't agree with you. When going for a poo knowing that it's going to be a bad one, you strain a bit too hard, resulting in a spray-like, liquidy jet of poo coating the inside of the toilet.

Oh man, that curry last night made me bumsneeze all the way through my shift.

I just did the worst bumsneeze, it actually caused pain.
