Shouting this name from your car to a random guy who is exercising or walking with a group of people. Normally you would do it to a fat guy and complimenting him that if he lost weight and that he looks good while making a John Travolta impersonation.
Guy in car: "Hey Figgy, is that you man? Oh my God you lost weight Figgy, you look good!"
"Figgy": confused and wonders if you're talking about him.
