Instead of writing they are drunk, teens post "Getting MWI" or mad with it.

Meanwhile, girls posting "Legal" are indicating that they are above 16 and legally allowed to have sex.

Teenagers on social networking site Bebo have created a secret language to stop adults knowing what they are up to, researchers say.

Youngsters are using slang words to keep parents and employers in the dark about their social activities such as partying and drinking.

Lisa Whittaker, a postgraduate student at the University of Stirling, who studied teens aged 16-18 in Scotland, said the slang had been created to keep their activities private, and cited the example of one young girl who was sacked after bosses found pictures of her drinking on the website.

Being in a relationship is known as "taken" or "Ownageeee", and " Ridneck ", a corruption of redneck, means to feel embarrassed.

She said: "Young people often distort the languages they use by making the pages difficult for those unfamiliar with the distortions and colloquialisms. The language used on Bebo seems to go beyond abbreviations that are commonly used in text messaging, such as removing all the vowels. This is not just bad spelling, but a deliberate attempt to creatively misspell words. By doing this they are able to communicate with their in-group and conceal the content from the out-group."
