Definition: A male chauvinist pig (MCP) was a term used in the 1960s among some feminists for some men, usually men with some power (such as an employer or professor), who believed that men were superior and expressed that opinion freely in word and action.
"Chauvinist" means someone who assertively maintains that his or her kind -- usually people of the same nationality -- are superior; "chauvinism" refers to an extreme and bigoted form of patriotism. Thus, "male chauvinism" was used to refer to an attitude of male superiority or male entitlement to power over women.
"Pig" was a word of derision used by some student activists in the 1960s and 70s to refer to police officers and, by extension, others with power.
Also Known As: mcp, m.c.p.
Examples: If that male chauvinist pig had lived twenty-five years later, he'd have been sued for sexual harassment!
