In ethology and social science, male bonding is the formation of close personal relationships, and patterns of friendship or cooperation between males.
In the context of human relationships, male bonding is used to describe friendship between men, or the way in which men befriend each other. The expression is sometimes used synonymously with the word camaraderie. The first widely noticed use of the term was in Men in Groups (1969; 2004) by anthropologist Lionel Tiger.
Male bonding can take place in various locations such as gyms, locker rooms, sport fields or courts, fraternities, and barbershops. This can include playing musical instruments, video games, business ventures, creative endeavors, journeys, quests, sporting activities, fishing, hunting, camping, gambling, social drinking, smoking cigars, working with tools, or even just conversing.
