a verbal instruction, guiding a driver of a truck/trailer in reverse. Literally meaning, "come on back." Originally from a racist joke about a garbage truck, e.g. What has 4 wheels, 2 legs and goes Momback? (or something like that)
driver: " I can't see the dumpster we gotta pick up. Can u get out and do the Mombacks?"
passenger: NP ... momback, momback, cut the wheel to teh left ... straighten out ... cool ... momback and ur good.
STOP DAMMIT!"
