mo back 

A parking lot attendant, usually of the African American variety and common in New Orleans tourist areas. This term is derived from the only two words you ever hear him say.

Car owner: "That mo back had us park on the far side of the lot even though there were three other spaces close by."
Mo Back: (while signalling someone to back into a spot) "mo back...mo back...mo back!"
