Ask HN: I acquired a 4-letter domain, what would you do with it?

The domain name itself isn't that important, it's generic: not a swear word or anything distinctive. I acquired it on a bit of a fluke for a deal, so I don't feel like I need to make my money back.

I was thinking I'd just do something fun/silly with it.

If you owned a 4-letter domain name where the name itself could be turned into anything, what do you think you'd do with it?

A url shortener comes to mind, but that's probably my technical background talking.
