www.urbandictionary.com/douche My personal favorite:
2. douche
A device used to scrub out a sordid, stinking, grungey, pussy.
Example:
Jeniffer's sickeningly filthy minge made the boys gag. So, Jason did the decent thing; he bought her a multipack of douches for Christmas. "Oh great!" She exclaimed. "Now my vagina won't smell of rotting seafood!" She went into the bathroom and got busy.
