n., A social movement of the late 2000's reacting to the stereotypical "bro" of the past.
Bromantics of the past exude tooliness; living their life to the full extent of their alleged "manliness", they engage in activities celebrating their sexual nature and physicality. Most are generally white who like to excessively exercise, speak in an inarticulate manner usually regarding the "chicks" and alcohol, and identify with brand names - specifically with brands like the Armani Exchange - in an attempt to care about their looks in a fashion unsuitable of Bromantics but appropriate for a metrosexual (although a metrosexual knows how to actually look good). The Bromantics seemed like a sect of homosexuality due to their obsession with mutual masturbation and porn viewing parties.
In response to this seemingly socially unacceptable life philosophy, men started banding together in ways that did not fit this social standard; their relationships developed from their sheer disdain of bro's. As time and the occurrence of these groups continued, a label of a "Post-Bromantic" was adopted as their "philosophia vitae"
