Best unused domain you own

Saw this post on twitter and participated. It then got me thinking and inspired me to do a similar post here to see what unused domain names that those on IH own.

As you can see, the post is getting a lot of attention. I think one thing that domain investors, indie hackers and those alike can all align on is domain names.

As a domain investor and aspiring indie hacker/maker myself, I, like many of you have the compulsion to register a bunch of domain names for all the cool ideas I get (most of which never get developed/made).

There are a few communities that I can think of where its members own a bunch of unused domain names, with IH being one of them.

So, what are your best unused domain names and tell me what the initial purpose/idea was for them.
