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!"
passenger: NP ... momback, momback, cut the wheel to teh left ... straighten out ... cool ... momback and ur good.
STOP DAMMIT!"

 Get the mombackmug.
Get the mombackmug. Hodedo originated in New York in the rush hour subways. It means, "Hold the door," used when the automatic doors are closing and someone wants to get into the already jam-packed car.
