Pre-fart 

The noise gas makes as it passes through your intestinal tract on it's way to your anus. Prefarts are most common after eating Mexican cuisine, brocolli, trail mix or cheap beer. Prefarts are oftentimes noisier than the actual fart they will eventually mature into, however unlike a fart --which you can soften the sound of by discreetly seperating your butt cheeks-- there is no way to manipulate your body to soften the deafening noise of the prefart. Most people will try to pass it off as their stomach growling, but since the sound emanates from a decidely lower point on your torso, no one is fooled and you would be better off to point at the dog or an old person nearby.

Must've been a Pre-fart....Stop pointing at my dog.

pre shit fart 

A pre shit fart, is the last bit of gas left over, which takes over the remaining space between your rectum , your poop and the air. It is the worst smelling fart ever, smells like you have shit your sefl, without actually shitting yourself. It is your last and final warning to get your butt to the toilet!

I have been busting ass all the way home, but this last one was a real pre shit fart.

It is the last amount before you are actually praire dogging. A preshit fart is allowing your company to actally smell the authenticity of what your shit would smell like if they were hagging out in the bathroom with you. Mostly, smells like a trucker shit.

Angel just threw a pre-shit fart and then dashed to the bathroom.....almost missing the bowl

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.
