A term used by bouncers or bartenders when kicking out an unruly customer. Concrete; meaning the front door, the sidewalk; embarrassing and in public but semi-safe. Whereas, Gravel means to be kicked out of the backdoor; where all the bartenders, bouncers, and regulars throw the unruly customer into a not-so-friendly environment, where there are no bystanders or cameras, and they all proceed to beat the shit out of the unruly one(s).
Nick the Bouncer: Hey! Was that you just breaking all those bottles?
Lil' shit kid: Yeah, so what? Fuck off! (spits at Nick the Bouncer)
Nick the Bouncer: Well, that's an easy answer to Concrete or Gravel? Boys, we got a live one! (Nick the Bouncer grabs the Lil' shit kid & throws him out the back door. Slow & steady, four regular Joes walk out the door cracking their knuckles).
