Jercum 

Getting high off your own supply in the most literal sense; shitting and pissing in a jar until it festers and you can huff it to get high

I’m gonna eat so eat weird so I can have the best jercum, just you wait

Jerkumcision 

when the dermis of the foreskin is rubbed painfully raw due to jerking off too much or without enough lubrication.

The shower hurt like hell after another unfortunate pornhub-induced jerkumcision. Took 3 days before I could use soap again.

Jencum 

A drug produced by fermenting human urine and feces in a bottle. A balloon is put over the bottle and it is all let sit in the sun. After a few days "cooking" the user removes the now vapor filled balloon and huffs the vapors, leading to a trip-like experience.

Common slang - Chim-chim, Butt Hash and Thai Fighting.

The Jencum is almost ready, lets give it to Larry.

jerumpkin

The act of practicing for a blumpkin by jerking yourself off while taking a dump.

I tried to give myself a jerumpkin as practice before my girl gave me a blumpkin.

jerumpkin shrapnel 

A poop stain on the back of the terlet(toilet)seat that is left after sitting too far back while performing a jerumpkin.

After finishing a very satisfying jerumpkin, I got up turned around and noticed jerumpkin shrapnel on the terlet seat.
