It is probably little-known that no other language contains more obscenity than English. In fact, 0.39% of the words appearing in the Oxford English Dictionary were deemed 'lewd' by a recent Government enquiry. The publishers of Viz have been tireless in their efforts to categorise the full diversity of English execration and this is the superb result of their ongoing efforts. It is unlikely that a more thorough attempt has been made to transcribe potty-mouthed vocabulary since Doctor Samuel Johnson's four-volume 'Lexicon of Ribaldry'. Regarded as the Holy Grail of profane scholarship, the manuscript (as reported by James Boswell) never came to light and is believed to have been destroyed by gypsies.
Anyway, I learned plenty here and I now employ words other than *@#& and *$@& - even when drinking among unemployables at 'The Swan and Anchor'! However, as well as many unusual expressions, one finds detailed definitions of more common terms. For example, @#%$%*ing is defined as the process of licking $%&@# (sometimes called %$@*#) from a $*#@$ or from an *%$# (which is, amusingly, sometimes known as a *&@#%!).
Among the less familiar words are a handful that have been taken from foreign languages and adopted into our own tongue. Surprisingly, the Germans have a verb for the act of *#@$%ing a Grandmother's $%*@#$ while having a *$#£@ inserted into one's £&*#@ by a transgendered dwarf with an unusually hairy #*£@$. Apparently $*%£@&$@#*%&?#%@&*£%#&?@$&@#&$*$%* is the longest known word for an obscene act (at 36 characters!). Strangely, despite common usage, it has yet to be officially accepted into the English language by the $*%£@&$@#*%&?#%@&*£%#&?@$&@#&$*$%*ers who produce the Oxford English Dictionary.
