The nickname of the old Grand Street Shuttle train that ran from 57th Street and Avenue of Americas to Grand Street in New York City in the 1980s, the cars used as R27s had every wheel with flat spots and made such a loud noise you can hear the train from as far as 5 stops away.
"Damn Jimmy what the hell is that loud noise in the tunnel?" Ah Tony that's the sound of the "Flat Wheels Local" and it sounds like its at 34th Street herald square right about now!

Get the Flatmug. Pounding it flat is the act of sex where the male takes authority and aggressively thrusts his penis into the vagina. Therefore pounding it flat would be a proper term.
