DON'T go stunting your pee, there's a piff breh. It may sound like gobbledegook, but it could end up in the Collins English Dictionary which is seeking the latest slang for a new edition.
Publisher HarperCollins has come up with a shortlist of words put forward by 14 to 18-year olds and has asked the social networking website Bebo to help pinpoint the most common slang terms in Britain.
Over coming months, Bebo's 10.5 million users will vote on the words they think should be included in the 30th anniversary edition of the dictionary.
"Teenage slang is notoriously hard to pin down if you rely on the normal channels," said Cormac McKeown, head of content at Collins.
"By the time it's filtered into publications, broadcasts, and eventually mainstream speech, it's too late, young people have stopped using it. "The findings from the Bebo community will give us the chance to keep track of an exciting part of our language that usually goes unrecorded." Among the slang terms proposed, "piff" means good, "breh" means boy and "shifted" means get arrested.
Other slang words are "stunting" (showing off), "pee" (money), "co-dee" (friends) and "pinky" (50 pounds).
The list also includes "sick" (cool, good) "bare" (a lot of), "seen" (cool), "mugged" (mocked), "fiend" (addicted) and "hater", which means a negative person.
A team of Collins experts will research the words' origins and decide which ones should enter the dictionary. Recent slang terms that have made it into the Collins dictionary include hoodies (hood-wearing youths) and WAGs (celebrity wives and girlfriends).
