If you want to go the old fashion route and actually look at a book (vs the web) and you're looking for old fashion crude language:
"Depraved and Insulting English - Words to Offend and Amuse" by Peter Novobatzky and Ammon Shea.
The book gives the word - pronunciation - definition - sometimes history of the word, usage and uses it in a sentence.
Some examples picked at random:
achilous / uh KAI lus / ajd - Having no lips.
One of may words scattered throughout this book that are used for describing common turnoffs.
"Wanda was a wonderful lady, but no matter what her attributes, J.B. could never bring himself to kiss an achilous woman."
chyme / KIME / n - Partially digested liquid food
"Rosemary's filthy-drunk roomate had ruined yet another dish with her careless vomitings: after all, the recipe called for parsley, sage, and
thyme, not chyme."
feist / FEIST / n - A silent fart.
"The disgusting and flatulent little toad from Word Processing was forever in the habit of letting loose with feists while lunching in the company cafeteria, and would always give himself away by tittering loudly when he did so."
gound / GOWND/ n - The crusty yellow substance that collects in the corners of one's eyes while one sleeps.
hypogenitalism / hi po JEN it ull ism / n - Stunted growth of the genitals
maritodespotism / mar it o DESS pot ism / n - Ruthless domination of a wife by her husband
omnifutuant / om nee FOO tyoo ant / adj - Prone to engage in sexual activity with anything
"Many readers were puzzled by the ad that ran in the Personals for several weeks that spring: Single Male Omnifutuant, seeking entity for romance on hot summer nights. Sex, age, species unimportant. Breathes oxygen a plus."
And two words that one would have to be very careful when using because there is only one letter difference but the definitions are completely opposite.
uxor
avalent / ooks or AHV uh lent / adj - able to have sex only with one's wife.
uxor
ovalent / ooks or O vuh lent / adj - able to have sex only with someone
other than one's wife
These are just a sample of some of the words in the 250 page book - many are a lot racier in subject....
Of course, if this isn't what you're looking for, sorry, but I hope it at least made you smile.
Take care all -
