Eminem making fun of drug myths adults tell kids to try to scare them away from using, along with the blame directed at him for possibly "causing" them to do drugs.
My favorite line in the song...Eminem, tongue firmly planted in cheek, going:
"And spinal fluid is final/You won't get it back/So don't get attached, it'll attack every bone in your back"
In one sarcastic line he devours this myth, as he actually realizes spinal fluid regenerates, like most things in the human body.
The dripping sarcasm throughout the song is sheer awesomeness. Really sucks it couldn't make it onto the "dirty" version of MMLP.
