look up any word, like crust punk:
 
1.
Slang. A person who fails to tip (stiffs) an employee that is normally tipped, such as bar and restaraunt wait-staff, pizza delivery drivers, hairstylists/barbers, taxi drivers, etc.
plural. stiffers
A good tipper gets their pizzas MUCH faster than the stiffer does.
Stiffers who don't tip their bartender often find themselves very thirsty.
