In professional wrestling, heat can refer to both crowd reactions and real-life animosity between those involved in a professional wrestling angle, or match. In terms of crowd reaction, heat is usually used to denote how much of a reaction a heel wrestler receives, but can also be used for a babyface. Although the term can in some contexts refer to either positive or negative crowd reactions, heat is usually used specifically to mean a negative crowd response (e.g. booing), with its opposite being a "pop" or positive reaction (cheering, clapping, etc.). As heat typically refers to a negative reaction that a wrestling character gets from a crowd in a performance setting, it has also become slang for a negative reaction that a wrestler gets backstage from colleagues, management or both. Backstage heat can be garnered for both real and perceived slights and transgressions. Cheap Heels can draw "cheap heat" (called "cheap" because it is an easy way for the villains to receive boos) by blatantly insulting the fans, a local sports team, or the town in which they are performing. Fan favorites would sometimes do the equivalent, referred to as a "cheap pop", by referring to the town (which Mick Foley popularized) or promising to "win one for the fans". The villains can also draw cheap heat by referring to a mainstream news event as part of their promo, especially if the event has strongly emotional or political ramifications (e.g. a natural disaster), although they sometimes do not mention it by name. Historically, another common practice of villains to draw cheap heat involves using racial and ethnic slurs to offend the collective sensibility of wrestling fans. For example, in 1972, when the American Indian Movement was gaining momentum, Baron von Raschke was known to refer to Native American WWA World Heavyweight Champion Billy Red Cloud as a "dirty low down Injun" as a means of drawing cheap heat. Another example of a wrestler using cheap heat was Sgt. Slaughter, who often delivered anti-American promos during the Gulf War (and Operation Desert Shield immediately before it) as part of his Iraqi sympathizer gimmick; one of those promos came at the 1990 Survivor Series, where Slaughter insulted servicemen stationed in Iraq for Thanksgiving. In 2003, The Rock used the Lakers-Kings rivalry to gain cheap heat during a WWE Raw show in Sacramento (The Rock even claimed that he was friends with Laker
