If you fancy popping out for a Ruby and a Britney tonight you might end up with a Leo Sayer.

Especially if you're out with a Wunch (as in a Wunch of Bankers), for a Frank and Pat (chat).

According to Cockney rhyming slang Web site LondonSlang.com, pub staff in London are increasingly being asked for "a couple of Britneys" as in Britney Spears. As rhymes with beers.

Leo Sayer has also entered the language it refers to an "all dayer", or 24-hour drink or rave binge. Other new additions include Tony Blair being rhyming slang for hair, as in "I'm off to get my Tony cut". And polo mint meaning skint: "I can't afford those shoes, I'm a bit polo this week."

IT geek-speak has also entered the realm of Cockney, as in Kryptonite or Wind and Kite (Web site).

The site is run as a hobby by Londoner Peter Walker, a computer engineer by trade. He has collated hundreds of sayings, including many we couldn't possibly publish.

These include an "aeroplane blond", a "Pat Cash" or a "Donald Trump", which can all be found on the site. ®
