Poo Choo Train

When sitting on the porcelain throne, preparing to drop some deuces a steady stream of fart air emits from your bunghole, sometimes pinched enough to emit a squeaking or whistling sounding fart announcing the turd train a'comin until the poo seals off the space and stops the whistle
Fuck dude, i could hear your poo choo train comin down the tracks from out here

Poo Choo Train Express 

All aboard the porcelain express!! You nestle down for what feels an epic. A high pitched fart whistles out of your puckered A-hole. There is an urgency like you never felt before.

With all your might you squeeze! Your muscles tighten just as your sphincter gives way! A mighty log of fecal matter and gas jettison out of your bungole on a one stop journey to hell! On its way down the log lays down a crooked rusty track that appears to be forged by satan himself.

The poo choo train express was quick, and brutal. It's all over in under 20 seconds. Looking down, the train wreck below leaves you sobbing in your crotch.
Kieran : Dude... go check the toilet. I think I may have caused some serious damage to my anus.

Derek : (runs to toilet - runs out) my god, are you ok? That's horrific.

Kieran : I don't know what happened. It was all over so fast. First a simple toot... then an explosion. I feel like I've been ass raped man!!

Derek : (comforts Kieran) hey big fella, it's gonna be ok. You just had your first poo choo train express. First time is never easy. It's gonna be a while before you're ok. We better go break the bad news to the toilet duck.

poo choo express 

The act of passing a blunt to the other end of the rotation. Making sure everyone is involved on the poo choo express. The first person says all aboard, the second makes the sound of a train starting, the third makes the says chuga chuga chuga poo choo, and so forth till it gets to the last person in rotation, and they makes a train braking sound. If that last person fails to make the braking sound, you'll end up with a train wreck. This also makes it so nobody can double hit.
There isn't enough room to sit in a circle, so we gonna have to get the poo choo express going.
