For entertainment that's not entirely mindless, check out www.urbandictionary.com.  It's an online version of what my friend Mark Lewellen and I once said we should do: a slang dictionary.  It's all user-written articles so it's similar to Wikipedia in that respect. 

  Some of the entries are actual attempts at explaining and defining the new and unusual ways people are using language, others are probably just someone trying to get others to use words in foolish ways, and still others are little more than petty insults aimed at someone else.  The common thread is that they're almost all entertaining.  Be warned: it's not for children, the faint of heart or those nursing, pregnant, or trying to get pregnant.  The language can be pretty hard core and some of the definitions are downright disturbing.

  My own humble submissions are under the name "poormanschef" if you want to see my contributions.
