I have an iPhone program called "Inspiro" which generates phrases, story ideas, etc. Great for improv or a random laugh. Got my blog domain idea "syncing dreams" from it, and I'm happy with that. No, it isn't checking for domain availability of course, but the combinations are unusual enough that you'll probably find the domain available. A few Inspiro results:
charmless koala
whispering playgrounds
day-glow demons
juicy naked mole rats
forging ice
You can generate different kinds of nonsense, like:
ruthlessly sneezing on perfect phrases
cheerfully grabbing handfuls of fascinated buildings
repeating naughty garden hoses
So, fun for strange ideas that make your brain get creative. My favorite tool for generating actual domain names though is easily http://impossibility.org/
this is kind of a tangent but kind of related: you can use a reverse dictionary (http://www.onelook.com/reverse-dictionary.shtml) as a sort of "multi word thesaurus" when trying to condense a couple of ideas down into one word
