Synonyms: "council", "common", "underclass" etc. Can be used as a noun or an adjective. Originally meant the lowest form of gypsy, i.e. not the genuine and generally peaceable Romany people, but the scum who nick caravans, tarmac drives and crap in your front garden. Now extended to mean anyone who claims benefits, lives in social housing or wears a baseball cap and white trainers with jeans to the pub.
"He lives on the pikey estate", "You drive a pikey Vauxhall Nova?", "What a bunch of pikeys".
Rear lights for a car which incorporate separate coloured lenses for each lamp (e.g. tail, indicator, stop) with the rest of the cluster given a mirrored finish. First used by Lexus on the IS200 model and since copied by Mazda on most of its cars and chavs on low-rent vehicles such as Saxos and Corsas. Probably the fastest way to ruin a perfectly good supermini.
Lexus have wisely dropped this style of light from their new IS250.
Man, I gotta get me some of those Lexus lights for my chavmobile.
