What's a good website subdomain?

I'm looking for a really good website domain that isn't boring.. things like byethost, webs.com, and weebly are what i call boring. Wix is good appearance-wise, but that's all. I'm looking to host a forum and community website. I'm fine with any kind of subdomain. The easier the sitebuilder system the better. I also need a rather large bandwidth as well as memory space, as well as a large array of templates that are unique. Anyone have any ideas?
