psilocybin farts 

That wonderful sensation when you're on mushrooms when it feels like you've got a pressurized CO2 tank full of ass-rip in your pants. And your stomach feels like there's a rock inside of it. These farts reek so bad that they could kill a small child or pet.

"Dude. I'm freaking out my stomach hurts."
"Just rip-ass dude, you've got the psilocybin farts."

psilocybin

A hallucinigenic compound found in various strains of magic mushrooms (native to many countries in England). Very potent, producing an intense trip. Typically, the trip lasts around 4-6 hours. It is a psychedelic trip with many colors and shape shifting, ect. Often one will have a rather philosophic come down (the stage of the trip where the effects are wearing off).
