Noun. Person, usually of the male gender, displaying traits of pop-collardness, land rover discoveryness (in some cases Jeep Liberty), plaid shortsness, and rainbow sandleness. Biffs can survive solely on their parents' credit card and starbucks coffee. A biff can easily be spotted in the winter months displaying its overpriced ski gear and drinking a latte, while simultaneously challenging twelve year old girls to a race down the mogul run of the most well observed section of the ski resort.
While entering the lift line, I noticed a group of biffs discussing the price of their designer sunglasses.
The party was packed with biffs. It was Biff Central Station.
