Bowl Reverb 

The extremely loud reverberation in the toilet bowl after you release a massive fart while taking a shit. This usually happens when you're trying to take a quiet, stealthy dump. Comes in 2 different forms:

1: Dryfire - Easily the loudest and most boisterous of the 2. Pure farts with no fecal matter; these happen from pushing hard or being constipated. These are so loud they could be heard from 30ft away or more with crystal clear clarity.

2: Explosive - These aren't as loud, but way nastier sounding. These happen with the occasional normal shit, and are 100% bound to happen with bad diarrhea. One of the nastiest sounds on Earth, but hilarious if you manage to hear them coming form someone else.

I was walking by the men's room at Taco Bell the other day, but had to stop and listen because someone had some intense bowl reverb. I came back to my table laughing my ass off.

Reverse Sand bowl 

The reverse sand bowl is when you put nesquik powder in your mouth and blow very hard onto your significant other's back and coating it.

We had such a fun time last night! My boyfriend did the reverse sand bowl on me and it felt amazing!
