punk

Uncertain. Possibly from punk (“rotten wood dust used as tinder”), attested since 1678, to anything worthless (attested since 1869) and then to any undesirable person (since 1908). The relatively tame 21st century usage of punk (“prank”, verb) was popularized by the American television show Punk'd (2003).

Unclear; first attested circa 1680 in writings about Native American practices, probably from Unami punkw (“dust”), though it has also been suggested it could be an alteration of spunk (“tinder”) (compare funk (“rotten wood”)).
