The greatest drug ever. Pioneered by Africans in the eighties, the jenk-development process involves defecating into a jar, putting a balloon on top, "fermenting" the product by letting it sit in the sun for several days, and finally inhaling the gas the forms inside the balloon.
Contrary to some urban myths, you can only get high off the jenk gas in the balloon, not the solid residue. Snorting the residue is commonly referred to as "jenkaine" which in fact does not get you high and is simply a poorly developed attempt at misinformation.
"Little boy, can you elaborate on the potency of this, jenk?"
"Old man, this is more potent than cannabis."
