Imitation police officer, such as a mall security guard. Derogatory term derived from the common slang for police officer "po-po".
Jane and Sarah ventured to the food court to meet up with John and Steve. Upon arrival, John bent down to give Sarah a kiss when Steve whispered "Look out, here comes the faux-po. Better cut it out before he comes over with his flashlight and night stick!"
Variation on po-po or police. A car that is similar to an unmarked poilce car yet is owned by a regular joe that wants to be a policeman or just wants to confuse others. Highly annoying when situated in the fast lane holding up traffic.
