The actress insists she's proud of her title - because it proves she was too refined to be an ""anal chugger"".
The Underworld star explains, ""They have these old drinking societies in Oxford and to join you have to drink a pint of vodka out of somebody's rainboot and things like that.
""There was this horrid thing, called anal chugging... There would be this rugby team... and they'd go off and get all sweaty and then one of them would come in the bar and pull down his trousers and pants (underwear) and then you'd pour a pint of beer down the crack of his a** and somebody else would have to be underneath, drinking it.
""This was why I was sixth most boring, because evidently there were five other people more turned off by this than me.""
