>>A few weeks ago I was talking about rhymning slang, usually attributed to cockneys, e.g.
>>
>>"Apples and rears" = stairs, "plates o' meat" = feet, "Lilian Gish" = fish, "dog & bone" = phone. The thing is that the rhymning bit isn't said, but is understood by the listener, e.g.
>>
>>"I'm putting on my daisies" - "daisy roots" - boots.

>>Last night I was surprised to hear, on TV, an American refer to "blowing a raspberry". If this is a common expression in the US then it would appear you use RS yourselves. This is short for "raspberry tart", so "blowing a fart"

>A 'raspberry' in North America is also a sound. I don't really know how it started being called 'raspberry', but in the ballparks, the 'bzzzzzz' sound blown out of one's mouth (usually at the umpire) by blowing with one's tongue between the lips was called a raspberry, and the context has moved out into common life. I don't know the context of the statement when you saw it on TV but is it possible you're looking for meaning that isn't there?

Yes, it's the sound I'm on about. Used as a sign of disgust or rebellion. The guy was talking about a celebrity blowing raspberries at, say, paparazzi. That sound is like that of a fart - hence "raspberry tart". Why else would a noise made with the lips and tongue be named after a berry?

Back home we have an expression "I'm brassic", meaning I'm broke/no money. I just accepted it as slang for many years, till I discovered it's short for "brassic lint" - skint (which IS UK slang for broke/penniless).

So the point I'm making that you may actually use similar rhymning slang without realising it.
