grebo englanniksi - Sanakirja.org (englanti-englanti)

(slang, UK, predominantly West Midlands) A greaser or biker; a member of any alternative subculture, as opposed to a chav or townie.
(slang, UK) A member of a United Kingdom subculture of the late 1980s and early 1990s, musically affiliated with garage rock and electronica, typically wearing baggy clothes and hair in high ponytails.

The highlight of my school days was one day in the mid-70s. There was a sort of glam-rock cult called the Grebos back then who wore smartish Disco clothes...
But the realistic side stepped in — y'know, if you're on the point of giving birth, you don't really need a bunch of grebos playing some dodgy old music downstairs.
...they were soon pigeonholed under the banner of "grebo rock"...
...focused on the hyper punk aspect of England's "grebo" movement...
This debut album is a glorious grebo-fest.
