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.
