A hurt locker doesn't sound like it is a good thing, but what does the phrase that has found common currency in a multi-Oscar-winning film actually mean?
With six Oscars to its name, the film The Hurt Locker is the toast of Hollywood. But what of the name itself? There's much speculation on the internet about the origins of the phrase, so what is a hurt locker?

The press pack for Kathyrn Bigelow's film claims "hurt locker" is GI slang for severe injury. But the film's writer, who picked up on the phrase during his time as an embedded journalist with an Explosive Ordnance Disposal unit in 2004, is rather more vague in his definition.
"If a bomb goes off, you're going to be in the hurt locker. That's how they used it in Baghdad," Mark Boal told the New Yorker. "It means slightly different things to different people, but all the definitions point to the same idea. It's somewhere you don't want to be."
Although American sports writers have used the phrase for at least two decades - to refer to injured players, or a team languishing in the league - the Oxford English Dictionary's first recorded example dates from 1966, says Fiona McPherson, senior editor of the OED's new words group.
"It's from a Texas newspaper and it says 'If an army marches on its stomach, Old Charlie is in the hurt locker'. Old Charlie is the Viet Cong. It is similar to the phrases 'world of hurt' or 'world of pain'.

"'Hurt' used adjectivally means something which causes suffering. As for 'locker', it's not only what soldiers keep their kit in, it's an enclosed space which can be hard to get out of."
But this piece of military slang has given a title to a poem about the Iraq invasion as well. In 2005, soldier-poet Brian Turner published Here, Bullet, a well-received collection of poems penned during his 11-month tour of duty in 2003-4. Among these was The Hurt Locker, which begins with the line "Nothing but hurt left here" and contains spare, sad stanzas on suicide bombers and snipers. "Open the hurt locker and learn/how rough men come hunting for souls."
