Searching the web can also be improved with Emacs.

(global-set-key (kbd "C-x g") 'webjump)

;; Add Urban Dictionary to webjump
(eval-after-load "webjump"
'(add-to-list 'webjump-sites
              '("Urban Dictionary" .
                [simple-query
                 "www.urbandictionary.com"
                 "http://www.urbandictionary.com/define.php?term="
                 ""])))

Webjump let's you quickly search Google, Wikipedia, Emacs Wiki and other pages. I've got it bound to C-x g.

This snippet adds Urban Dictionary to the list of pages, so the next time you wonder what those dastardly kids mean when they write faceroll or sassafrassa or Technotard or kthxbye or whatever else is hip these days, well, then you can find out. With webjump.
