bum sneeze

When you blow your nose or sneeze and you let a fart go by accident. Can also be used to to simply describe a fart on it's own.

I was blowing my nose when a bum sneeze slipped out.

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.
