Roger's Profanisaurus has long been one of the most popular sections in Viz Comic. And now, as the magazine celebrates its 45th year disgracing the shelves of shops in Britain and around the world, we're pushing out our beefiest ever volume of foulage - Roger's Profanisaurus: Turtleshead Revisited.

Each issue of Britain's funniest* magazine sees readers suggesting more hilarious definitions to add to our potty-mouthed dictionary of rude words, filthy phrases and appalling euphemisms. And now we've brought the whole thing together in this tastefully designed 700-page cistern-smasher of a book - Roger's Profanisaurus: Turtleshead Revisited. (*publisher's estimate)

Containing more words than the whole of the Lord of the Rings trilogy (no, really), Roger's Profanisaurus : Turtleshead Revisited is a filthy romp through the filthiest (and funniest) sewers of the English language, with each eye-popping definition exhaustively cross-referenced for greater clarity. If you don't reach for your copy next time you're applying for a job, writing a wedding speech, or roughing out a police statement, you really will be missing a trick.
