Back-road in Mexico
A term used by Gearheads and Street Racers used to cover up where they have actually done some dumb shit, such as drag racing, top speed runs, drifting, etc, to avoid getting into trouble with the police.
"I took my G-Body Cutlass out and managed to beat some kid's Foxbody on a back-road in Mexico last night! That supercharger is starting to pay off!"
