My home wifi is my phone number -- I make it simple (though, I probably should make it more complex and make the guest one my phone number... then again, I won't let guests connect to my wifi unless they're staying long, and even then they need a good excuse... ).
As for my phone's hotspot -- I have it as my phone number as well. I don't want to type a lot when I have to connect to it. It is fun to go out and randomly turn on my hotspot.... simply because of the hotspot name...
...which, I can't give out here because... well... it'd be inappropriate.
It was the common numbers, but that just started an argument on where the 0 goes..
