Hah, I bought that URL a long time ago, mostly as an in-joke between me and some friends since Bruce Willis was my favorite actor. Then later I needed a dev URL for some work I was doing, and the only one I had free was brucewillis.sexy. Then I kept making subdomains on it for different things and eventually it just became the default.
[1] https://git.brucewillis.sexy/~tombert/fs_index I promise, safe for work, despite the URL.
