"White trash" is a derogatory American English racial slur referring to poor white people, especially in the rural southern United States. The label signifies lower social class inside the white population and especially a degraded standards of living. The term has been adopted for people living on the fringes of the social order, who are seen as dangerous because they may be criminal, unpredictable, and without respect for authority whether it be political, legal, or moral. The term is usually a racial slur, but may also be used self-referentially by working class whites to jokingly describe their origins or lifestyle.
In common usage, "White trash" overlaps in meaning with "cracker" (regarding Georgia and Florida), "hillbilly" (regarding Appalachia), "Okie" (regarding Oklahoma origins), and "redneck". The main difference is that "redneck," "cracker", "Okie", and "hillbilly" emphasize that a person is poor and uneducated and comes from the backwoods with little awareness of the modern world, while "White trash" emphasizes the person's moral failings.
The term White trash first came into common use in the 1830s as a pejorative used by house slaves against poor whites. In 1833, Fanny Kemble, an English actress visiting Georgia, noted in her journal: "The slaves themselves entertain the very highest contempt for white servants, whom they designate as 'poor white trash'".
In 1854, Harriet Beecher Stowe wrote the chapter "Poor White Trash" in her book A Key to Uncle Tom's Cabin. Stowe wrote that slavery not only produces "degraded, miserable slaves", but also poor whites who are even more degraded and miserable. The plantation system forced those whites to struggle for subsistence. Beyond economic factors, Stowe traces this class to the shortage of schools and churches in their community, and says that both blacks and whites in the area look down on these "poor white trash".
By 1855, the term had passed into common usage by upper-class whites, and was common usage among all Southerners, regardless of race, throughout the rest of the 19th century.
