The act of macking on with multiple people on one occasion. Often the city of mack is visited during a "mack competition" where participants compete and the winner is decided based upon who has macked on with the most people in the given period, for example during a night out clubbing. A rendition of Rack City - Tyga is often sang whilst in mack city, replacing the word "rack" with "mack".
