bowl blaster

An extremely loud, smelly fart. It doesn't necessarily have to be done on the toilet bowl.

I just had some Mexican food, so you know I'm going to have a bowl blaster soon!

horizontal bowl blaster

A term used when one evacuates their bowels in a particularly furious manner, and in doing so gets fecal matter UNDERNEATH the toilet seat.

Man... Rufus just unleashed the horizontal bowl blaster and completely ravaged your toilet.
