The word Bro was originally an abbreviated form of "brother". But since the end of 1999, the word began to be used to refer other man, like "guy" or "fellow."
And as the technology world evolves, the word became associated with young men which were "conventional guys' guys" who spend time partying in ways similar to each other. The word is also associated with guys wearing frayed-brim baseball hats, oxford shirts, sports team T-shirts, cargo shorts, and boat shoes or sandals.
The applications of "bro culture" can be correlated to words like "brogrammer" and "curlbro". According to the Oxford Dictionaries, the term "lends itself" to combinations such as "bro-hug" and "bro-step" and portmanteaux such as "bromance" which was first recorded in 2001.
While the word >em>bro is to describe the male youth subculture, the popular image of bro lifestyle lacks the consistent definition. Oxford Dictionaries noted that bros have frequently self-identify themselves with neologisms containing the word "bro" as a prefix or suffix.
In 2013, a New York Magazine article by Ann Friedman said that:
As a result, the playful "bro" modifiers became responsible for making the subculture ripe for mockery, and routine harassment on women.
