A nickname for the cheap, fortified wine by the name of Cisco.
It's often called a "bum wine" because of how cheap it is (plus you have to be a full on alcoholic and/or bum to not think it tastes like shit)
Best thing to drink if you want to get fucked up and wake up in some odd place and not know how you got there. Drink a good amount of it, and you're almost guaranteed to go on a violent rampage and wake up naked in a field with a hooker named Shantiqua who's Adam's apple is bigger than yours.
Yo, wanna run up to ABC Liquor with me to get a couple bottles of liquid crack? I feel like getting tipsy as fuck tonight."
