Something like punk has been smoldering in American English for hundreds of years, undergoing drastic changes of meaning from century to century. It began as a bizarre kind of overcooked corn, explained in a 1618 account of certain Indians in Virginia: "Some of them, more thriftye then cleanly, doe burne the coare of the eare to powder, which they call pungnough, mingling that in their meale, but yt never tasted well in bread or broath." Around that time, also, punk was a word for "ashes" in the Delaware Indian language.
A couple of centuries later, punk had become a word for the slow-burning sticks used in kindling fireworks. By 1889 it was a slang term for a cigarette, and by the end of the century punk had a sense "worthless" as in a story by George Ade: "And this crowd up there was purty-y-y punk."
Today's first meaning of punk, a small-time hoodlum, developed in the period between the World Wars. And in the late 1970s punk came to designate bizarre clothing and body decorations associated with loud and aggressive rock music. To the general public, it still has an unpleasant taste.
