A bromance is a close, emotionally intense, non-sexual bond between two men. It is an exceptionally tight affectional, homosocial male bonding relationship exceeding that of usual friendship, and is distinguished by a particularly high level of emotional intimacy. The emergence of the concept since the beginning of the 21st century has been seen as reflecting a change in societal perception and interest in the theme, with an increasing openness of society in the twenty-first century to reconsider gender, sexuality, and exclusivity constraints.
