'Wardrobe malfunction' enters dictionary

The term "wardrobe malfunction" has been included in the Chambers English Dictionary for the first time.

Justin Timberlake made the euphemism famous in 2004 when he made a public apology for accidentally exposing Janet Jackson's right breast at the Super Bowl. The pair had been performing a duet at the half-time show when Timberlake tore off a section of Jackson's costume.

In its latest edition, Chambers Dictionary defines the phrase as "the temporary failure of an item of clothing to cover a part of the body that it would be advisable to keep covered".

WAGs, nail bars and social networking also make it into the dictionary for the first time.

Mary O'Neill, editor in chief, said: "The new words paint a vivid picture of current interests."

Revealing the strict selection process for words and phrases, she added: "We've been watching words like WAG for a long time but we don't want words that are ephemeral or just the buzz words of the moment."
