Cockney rhyming slang has got to be the illest regional slang used anywhere in the world.
trouble & strife = wife
loaf of bread = head
apple & pears = stairs
titfer (from tit-for-tat) = hat
tom (from tomfoolery) = jewelry
bread & honey = money (why we call money "bread")
raspberry tart ... ever wonder why some people call farts raspberries?
The best usage has to be calling one's "ass" their "bottle and glass" then rhyming "Aristotle" off of bottle, shortening Aristotle to "Aris," rhyming that with "Plaster of Paris," then landing on "plaster" as slang for ass. Wow.
