Dump cig

A 'found' cigarette or cigarette butt greasy people will pick up and smoke. Whether it be from an ashtray, on the ground, or more literally in the trash.

Grub: "You seriously gonna smoke that dump cig? That's greasy man."
Me: "It's the half smoke I just put out ten mins ago. It's not like I just picked it up off the ground like a smelly crust punk."
