In Chicago the "shine line" is what the CTA calls the Red Line. It is called this because mostly black people ride it. It runs from Howard to 95th street on the far south side.
Shit bro I'm at 95th and need to get to Fulerton quick to sell some weed.

Damn son day one shit, why dont you just take the shine line?

Get the shine line mug.
Very skimpy amount of a "drug," per se. Providing or consisting of less than is needed; as little a line as possible
"Damn, you have a whole green 80, and all you are giving me is that SHINE LINE?!" "Man, can y'all bust up w/ me?! Shit, yea, but you are getting just a shine line..."
