Ralph 

An auto-mobile based game originated in Montgomery County, Maryland which involves shouting "Ralph" from a moving car at random pedestrians. The goal is to make the pedestrian(s) turn around in confusion as the car members have a good laugh. DRIVERS ARE NOT TO WATCH REACTIONS, THATS HOW ACCIDENTS HAPPEN. The only known counter to being Ralphed as a pedestrian is to say "Gucci!" back to the Ralpher. If such a rare event occurs, the Ralpher is barred from Ralphing for life.

Driver: Yo Ralph that fat guy!
Passenger: I can't man I got Guccied last week.
