peckerwood
What does peckerwood mean?
Inside, a white inmate — particularly one tied to the white-power prison subculture. Originally a Southern Black slur for poor rural whites (pecker + wood, an inversion of woodpecker), it got flipped and worn as a badge by white prison gangs from the 1940s onward. Shortened to 'wood' in everyday yard talk.
Origin
19th-century Southern Black English inversion of 'woodpecker', used as a slur for poor rural whites. Reclaimed by white prison gangs in mid-20th-century California as a self-identifier.
