My friend Bill told me about the nifty site Ironic Sans, and from there I discovered this post about the short-synonym service called Thsrs. As a word-guy, this really tickles me. So I quickly whipped up a Keyboard Maestro macro to make look-ups easier. The macro is illustrated below or you can downloaded at this gist.

Yes, there's probably some nifty Javascript bookmarklet way of doing this. But my hammer is Keyboard Maestro and I want to be able to use Thsrs from any app, so this suits me better. (Not that I wouldn't like a JS solution, too.)
