An event at which high concentrations of bros are present. Although sexual activity between aforesaid bros is typically absent, it is understood to be liable to erupt at any given time. A portmanteau of the the words "bro" and "orgy."
"We are the Borg. Lower your trousers and surrender your brassieres. We will add your biological and technological concupiscence to our own. Your culture will adapt to service our Borgy. Resistance is futile."
An orgy of only bros. A traditional brogy consists of a minimum of atleast four bros. A euphoric culmination of bros bro'n out. Unlike an actual orgy there is no penetration of any kind due to the fact that bros are only present. Also clothes are not optional at a brogy but required. Backwards hats and neon colors are highly recommended attire. Common activities of a brogy include watching Entourage or other HBO series, drinking brew, conversing about past sexual encounters with females and listening to Jam Bands among various other bro favorites.
