...have a random word function? By this, I mean you click something like "Random Word", for instance, and a random word pops up.

Preferably ones coming in a "SFW" format, but if not, that's fine too.

SFW = Safe For Work.
Well, you can always go to dictionary.com, hit your head off the keyboard, hit enter, and see what suggestions come up. I checked, it usually works.
Not a dictionary.. and maybe not SFW... but:

In response to Metamorphman
Or, specifically a dictionary:

But it seems to give you words in other languages.
