white trash (n.)

1824年，最初出现在南方非裔美国人的方言中。

The slaves themselves entertain the very highest contempt for white servants, whom they designate as 'poor white trash.' [Fanny Kemble, journal, Jan. 6, 1833]

“奴隶们对白人仆人非常鄙视，称他们为‘可怜的白人垃圾’。”[范妮·肯布尔，日记，1833年1月6日]

[T]he term [poor white] is rather loosely applied by Northern writers even to mountaineers and to small farmers who live on a precarious footing. But in the Southern conception, not everyone who is both poor and white is a "poor white." To the Southerner, the "poor white" in the strictest sense is a being beyond the pale of even the most generous democratic recognition; in the negro's term, "po' white trash," or so much social débris. [Robert Penn Warren, "The Briar Patch," 1930, footnote]

“‘可怜的白人’这个词汇在北方的概念中，甚至被宽泛地应用于山民和靠不稳定生计为生的小农民。但在南方的概念中，不是每个既贫穷又是白人的人都是‘可怜的白人’。对南方人来说，‘可怜的白人’在最严格的意义上是一种超出最慷慨的民主承认范围的存在； 在黑人的术语中，是“贫穷的白人垃圾”，或者说是社会上的废物。”[罗伯特·佩恩·沃伦，“荆棘丛中”，1930年，脚注]
