P.T.A.R.T.
P. T. A. R. T. is what taxi drivers yell when they see Uber and Lyft drivers making more money than them. It means they're tired of getting screwed over by app drivers.
"PTART! You're all a bunch of losers!", A taxi driver seeing a Uber driver park right in front of him.
"PTART! I'm gonna charge you extra for being a moron!", A taxi owner seeing a Lyft driver take 10 customers in one night.
"PTART! I'm gonna hit you with a taxi pole!", A taxi driver who just saw a Uber driver take his last customer."
