Timothy McSweeney: THE BROCYCLOPEDIA 
The bra, as distinguished from the bro or the broseph, tries as much as possible to emphasize his physical prowess. A bra spends much of his waking hours in the gym “liftin’” with his other bras. The bra can be most easily identified by his sleeveless Abercrombie & Fitch T-shirt and backwards baseball cap. A bra is most at home in a setting where he can punch another comrade in the chest and refer to him as his “bra.”
I am still laughing.
