If a teenager said the words (above right) to you, should you be offended or flattered?

The answer, thankfully, is flattered, since a rough translation is "Wow! You are the coolest person. Do you want to hang out at my place?"

Society is more geared than ever to young people, but their slang - and the speed at which it changes - can be a mystery to those old enough to vote.

This coded language designed to exclude adults is being used to tempt would-be teachers into schools - the latest campaign by the Teacher Training Agency includes a poster which asks "Linguists. Would you like to learn new words?"

So which words are current in the classroom? E-cyclopedia, the Magazine's guide to matters of linguistic interest, has compiled this guide. The main influences seem to be Creole patois and rapper slang.

Wanna roll with Vicky and the gang?

It is by no means an exhaustive list, though we hope that with your suggestions it will become more complete. Nor will you find the likes of "chav" or even "chavtastic", which this week proved their mainstream usage by making it into the Collins English Dictionary.

But a health warning to non-teens - use this slang at your own risk. Not only will it sound desperately lame issuing from your mouth, chances are it will be out-of-date by the time we hit the "publish" button.

ah nam - tell on, rat on.

back slang - a code which uses the original spelling of words and adds extra letters and syllables for effect or to disguise the real meaning. The rap lyric "shizzle my nizzle", which confounded a High Court judge, is one such example.

(Suggested by reader Jason Truman, Leamington Spa)

rago - whatever, OK.

random - odd, irregular, crazy, out there. Not used when something is genuinely random, but as an adjective by those who like to think they live a life less ordinary and have a wacky sense of humour. An example from Urban Dictionary reads thus:
Teen 1: "Cheese! hahahaha"
Teen 2: "Wow! That's sooooo random!"
Also used by players of the online game Counter-Strike to describe someone whose performance is inconsistent.

(Suggested by reader Abtin, Berkhamsted)

yard - house, garden, where one lives and hangs out.

your mum - a comeback to a question or insult. An implied affront to one's mother, which may be taken as an ineffectual insult or may result in grievous bodily harm.
