Lots of people love all things British. Me, I love both Australian and British accents and the amazing slang terms which spice up those different versions of our common language.
I found this English slang site which lists some great examples of terms we Americans very seldom hear, several very risque', for instance...........
aeroplane blond - one who has dyed her hair but still has a 'black box"!
back wheels - balls, testicles. An example of this would be "Cor, I got a great blowjob last night, she even got me back wheels in!". You could also use vulgar terms like "Right up to the back wheels" etc.
beer scooter - the ability to get home after a night out on the booze and not remember it, i.e. "I don't even remember getting home last night, I must have got the beer scooter".
Bruce Lees - erect nipples (as in a pair of hard 'nips').
bunny boiler - an unhinged and overly possessive woman. From the rabbit boiling scene in the film "Fatal Attraction", e.g. "I don't like the look of her mate, could be a bunny boiler".
feeding the pony - to arouse a woman using one's digits ! Also see 'badger scratching'
greyhound - a very short skirt. From the fact that a greyhound (on a race track) is close to the hare (hair), i.e. "Blimey, look at the greyhound on that bird!".
mumblers - used when you spot an attractive girl in tight shorts or similar clothes, i.e. you can see the 'lips' moving but can't quite make out what they're saying.
Folks, you can spend all day on this site and not find all the wonderful colloquialisms there. If you want to indulge a little farther, here is a link to a selection of Australian slang sites, some of which use rather colourful language.
