A person who is fat, socially awkward, extremely unathletic, and permanently smells like a mixture of body odor and farts. The central wardrobe items in every beefer's closet are tapered sweat pants, novelty t-shirts, flannel and jean jackets. Beefers typically sweat 8-10 times more than their non-beefer counterparts, and have armpit stains within 30 minutes of showing and dressing in the morning. Easily identifiable by their dirt staches, horrid breath and die-hard love for the game of hockey. Only males can be classified as a beefer.
Person 1: Did you catch a whiff of those fat losers trading hockey cards in the K-Mart parking lot yesterday?
Person 2: Yeah, what a bunch of beefers.
