The concept of toxic masculinity is used in the social sciences to describe certain traditional standards of behavior among men in contemporary American and European society that are associated with detrimental social and psychological effects. Such "toxic" masculine norms include dominance, devaluation of women, extreme self-reliance, and the suppression of emotions.
Conformity with certain traits viewed as traditionally male, such as misogyny, homophobia, and violence, can be considered "toxic" due to harmful effects on others in society, while related traits, including self-reliance and the stifling of emotions, are correlated with harm to men themselves through psychological problems such as depression, increased stress, and substance abuse. Other traditionally masculine traits such as devotion to work, pride in excelling at sports, and providing for one's family, are not considered to be "toxic".
Toxic masculine norms are characteristic of the unspoken code of behavior among men in American prisons. The term toxic masculinity has also been used by some in the mythopoetic men's movement in contrast to a "real" or "deep" masculinity that they say men have lost touch with in modern society.
The concept of toxic masculinity is used in the social sciences to highlight the idea that some traditional norms of masculine behavior – ideas of how men should behave – are in fact harmful to men, women and society overall. Terry Kupers, a professor at The Wright Institute school of psychology, defines toxic masculinity as "the constellation of socially regressive male traits that serve to foster domination, the devaluation of women, homophobia and wanton violence". The concept of toxic masculinity is not intended to demonize men or male attributes, but rather to emphasize the harmful effects of conformity to certain traditional masculine ideal behaviors such as dominance, self-reliance, and competition.
