Cartoon character Homer Simpson's catchphrase has made it into the updated online edition of the Oxford English Dictionary published today.

"Doh" is now an official word of the English language.

Chief Editor John Simpson said: "My job is the perfect excuse for watching action films, soaps, quiz programmes - where the language is busy right now."

Inspiration for new additions to the dictionary were taken from a wide variety of sources - from teenage chatter, the pop music charts and even Bridget Jones's Diary.

Although "bad hair day" has been around for some years, it was the neurotic Londoner's use of this phrase in the best-selling novel that prompted the dictionary to include it to describe times when things aren't going quite right.

Bollywood - the Indian version of the US film industry Hollywood - now also has an entry in the dictionary.

And the new meaning for the Full Monty that arose after five unemployed steelworkers became male strippers in the film of that name in 1997 gets an entry. The Full Monty now means to be naked.

Another new entry is "new man".

Originally, the term was used by the Christian Church in the 14th Century for anyone spiritually renewed - but now it refers to a man in touch with his feminine side.

Going to discos is now officially called "clubbing."
