Crank-junk

Another name for methamphetamine
Based off the older nickname "crank" combined with the fact that meth has a decent amount of MSM cut into it.. MSM is junk.. and meth is crank.. when u got em together you got crank-junk..

Crank-junk is commonly consumed in a "crank-junker" water pipe... the process called "junk-railing"
