Making clothing out of scraps that people would otherwise discard. "Another man's trash is another man's treasure" mentality.
While "Junk Punk" may use scraps and "trash" the objects found on the clothing are completely reusable and in good shape. A style of recycling taken to an extreme.

Girl: I think you mean "scallawag," sir.
Dude: Fine, whatever, why are you wearing trash?
Girl: It's not trash, it's Junk Punk! *leadpipetokidney*
