Styrofoam

Basic facts
A dope-ass material used to make life-saving containers from which a person could sip lean. If a person is too poor to afford a styrofoam container from which to sip lean from, an option is to opt to sip lean from ones mudjug as a replacement. This is seen as thoroughly disgraceful and is associated with the lower class of citizens.

Appearances
Orangou has been known to mention this material in his raps. He references the material in "Blue Cheese" 13 seconds into the song, in the context of "sipping lean" from it.
