The Full Form of PWT is‍ Poor White Trash.

White trash is a “racist and classist slur” used in American English to refer to poor white people, especially in the rural southern United States. The label signifies a social class inside the white population and especially a degraded standard of living. It is used as a way to separate the “noble and hardworking” “good poor” from the lazy, “undisciplined, ungrateful and disgusting” “bad poor”. Use of the term provides for middle- and upper-class whites a means of distancing themselves from the poverty and powerlessness of poor whites, members of a privileged class (i.e. whites) who cannot enjoy those privileges.

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 political, legal, or moral authority. While the term is mostly used pejoratively by urban and middle-class whites as a class signifier, some white entertainers self-identify as “white trash”, considering it a badge of honor, and celebrate the stereotypes and social marginalization of lower-class whiteness.

In common usage, “white trash” overlaps in meaning with “cracker”, used of people in the backcountry of the Southern states; “hillbilly”, regarding poor people from Appalachia; “Okie” regarding those with origins in Oklahoma; and “redneck”, regarding rural origins; especially in the South. The primary 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 and interaction with the modern world, while “white trash” – and the modern term “trailer trash” – emphasizes the person’s supposed moral failings, without regard to the setting of their upbringing. While the other terms suggest rural origins, “white trash” and “trailer trash” may be urban or suburban.

Scholars from the late 19th to the early 21st century explored generations of families who were considered “disreputable”, such as The Jukes family and The Kallikak Family, both pseudonyms for real families
