diarrhea fart 

An emission of noxious gas from one's anal cavity which has the distinct smell of diarrhea.

As we were all chilling at the party, Julie ripped a diarrhea fart that cleared out the entire room with its vicious smell.

pre-diarrhea fart 

That fart that is so god-awful and carries a signature smell that you know you're going to have diarrhea soon.

I was sitting at the table in the restroom and let out a pre-diarrhea fart. It smelled so bad everyone around me starting gagging. I then proceeded toward the restroom as soon as possible.

Diarrhea Echo Fart 

(D.E.F.) That amazing sound that your ass projects against the toilet bowl when you have a backed up shit waiting to immensely emerge from your balloon knot worm hole.

I was sitting on the toilet and almost busted my ear drums from the sound of my diarrhea echo fart hitting the toilet bowl.
