British boozers have been sharing bizarre drunk photographs in colourful costumes with the world on a series of "50 Shades Of..." pages.
50 Shades Of Burnley features bizarre pics of an overturned car and a reveller dressed in a dayglo mankini, while the Ribble Valley's site shows a pair of party queens flashing their pants, the Daily Star reported.
Although more than 42,000 users have 'liked' the groups, campaigners have called for Facebook to take down the pages.
Blackburn MP Jack Straw has branded the pages as "unpleasant and abusive," while Burnley MP Gordon Birtwistle called the groups "outrageous and disgraceful".
A spokesman for the social networking site said that the pages did not break its Statement Of Rights And Responsibilities.
