abbreviation of Montclair, VA, like how LBC is
short for Long Beach, CA. A suburban community based around Lake Montclair and a golf course.
Montclair, where there is nothing to do but drink,
smoke, and piss off upper class middle-aged
white people.
Kid 1: Man, the MTC is so boring.
Kid 2: Wanna chug a 40, smoke a bowl, and egg some cars on Waterway?
Kid 1: Fuck yeah!
