such as when women are assertive or aggressive, or when men are passive or servile. According to James Coyne from the Department of Psychology at the University of California, "'Bitch' serves the social function of isolating and discrediting a class of people who do not conform to the socially accepted patterns of behavior." In the context of prison sexuality, a bitch is a lower-hierarchy prisoner, typically physically weak or vulnerable, who is dominated by more senior prisoners and forced to adopt a servile role. According to convention, these inmates are used as sexual slaves or traded as personal property. A "prison bitch" can also refer to any subservient entity, as in the Douglas Rushkoff description of a Microsoft - Yahoo partnership: "Yahoo is merely hooking up with the most alpha male company it can still find in order to survive. Microsoft will soon turn Yahoo into its prison bitch, and this won't be pretty." Idioms Son of a bitch The first known appearance of "son-of-a-bitch" in a work of American fiction is Seventy-Six (1823), a historical fiction novel set during the American Revolutionary War by eccentric writer and critic John Neal. The protagonist, Jonathan Oadley, recounts a battle scene in which he is mounted on a horse: "I wheeled, made a dead set at the son-of-a-bitch in my rear, unhorsed him, and actually broke through the line." The term's use as an insult is as old as that of bitch. Euphemistic terms are often substituted, such as gun in the phrase "son of a gun" as opposed to "son of a bitch", or "s.o.b." for the same phrase. Like bitch, the severity of the insult has diminished. Roy Blount Jr. in 2008 extolled the virtues of "son of a bitch" (particularly in comparison to "asshole") in common speech and deed. Son of a bitch can also be used as a "how about that" reaction, or as a reaction to excruciating pain. In politics the phrase "Yes, he is a son of a bitch, but he is our son of a bitch" has been attributed, probably apocryphally, to various U.S. presidents from Franklin Roosevelt to Richard Nixon. Immediately after the detonation of the first atomic bomb in Alamogordo, New Mexico, in July 1945 (the device codenamed Gadget), the Manhattan Project scientist who served as the director of the test, Kenneth Tompkins Bainbridge, exclaimed to Robert Oppenheimer "Now we're all sons-of-bitches."
