Boris?

"In early May 2008, the newly elected Mayor of London Boris Johnson announced that drinking of alcohol would be banned on public transport from the start of the next month. Many people then thought up the idea of a Circle Line Party to be held at the end of the month to celebrate the last night of legal drinking on the London Underground, and spread the idea on the social networking website Facebook. The plan quickly received media attention and was mentioned in several newspapers. [1]

On 31 May 2008, the night itself, thousands of people attended, the largest Circle Line Party ever. Some had come in costumes ranging from 1920s prohibition to dressing up as Boris Johnson himself. Although mostly peaceful, seventeen people were arrested by police due to disorderly behaviour, six tube stations were closed and eventually the entire Circle Line was suspended for the rest of the night.

Hatred for London's new mayor was rife along the Circle Line as partygoers jumped up and down singing "Boris is a wanker" in unison." from Wikipedia
