So? If the article was posted on Yahoo or some other mainstream US news site the commenters there wouldn't know what it meant either. It's not American slang, it's gay slang.
Was about to say a publication like Daily Mail shouldn't be stooping that low, but they're already scrapping the bottom of the barrel when it comes to journalism, so carry on.
US based news publications wish to desecrate and dumb down the English language for the benefit of it's native population, that's fine but in the UK, we respect our native language and have no wish to have it diluted by useless US drivel.
nnnnnnn the pretentiousness Go choke on some fish and chips.
