means A raw, stripped-down style of rock music built on short, fast songs and a DIY, anti-establishment attitude.

from 'Punk' had been slang since the 1500s-1600s for worthless stuff, then rot, then a petty hoodlum — a word that climbed up from the gutter. By the mid-20th century American critics were calling scrappy garage bands 'punk rock' as an insult, celebrating their lack of polish. The bands of the mid-1970s — in New York clubs and London squats — grabbed the slur and wore it as a badge, turning 'worthless' into a whole movement's name.
