Barry

More specifically "having a Barry", and it is one of the better examples of twice-removed Australian rhyming slang. It means you're having a bad time of things, or a shocker. The connection is Barry Crocker, an extremely naff singer from Geelong, Australia (my home town - carn the Cats!) who sang the original theme song to Neighbours and is usually seen these days singing at telethons or Carols by Candlelight or other such horseshit. In a nutshell, shocker = Barry Crocker = Barry. Most often used in a sporting sense, when someone asks how you performed. PS for the Seppos out there, Neighbours is a cheap and nasty Aussie soap opera that the Brits can't get enough of. BTW, "Seppo" is another example of Aussie rhyming slang, meaning American (Yank = septic tank = seppo)
