That wonderfully white powder that is oh so pleasing when snorted up one's nose. Also known as yay or coke or cocaine, this strong stimulant creates a very intense, short-lived, and addictive high, to be soon followed by a longer-lasting and equally intense come down which can be depressing and sleep-inducing.
Josh loves snorting yayo so much, he binges for 36 hours straight. After the 36 hours are up, he comes down and bugs out, fiending whole cartons of Marlboro Red cigs.

Cocaine. This is a wonderful drug, but be careful. If you snort it wrong you can die, and come downs are a bitch.
