Dirt rock

Meth whores and girls that sleep with drug dealers in general to get free drugs.

Jamie is such a fucking dirt rock! She's giving Mike head right now as we speak so he will give her free dope.

Off-one

To get sober. Or more commonly referred to quitting methamphetamines.

Hey, I'm sorry but I can't chill with you guys at the tweaker pad anymore...I'm trying to stay off-one for good.
