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?
These are not just regular fat kids. They are fat, athletic men on the offensive line who can turn and run at any moment, skip pull and ram with the utmost efficiency, and rub a little nasty on their opponent (i.e. Tea-bag). Some may call beefers by another alias which is willmanites. The select few in this brotherhood are joined together by one name, the Beefer Nation. The 2008 offensive linemen for the Permian high school football team are the original founders of the Beefer Nation, and therefore have the privilege to elect other people as beefers.
Man did you see all those beefers?!....No those are just fat kids...
