It's totally normal.
I had an issue with my modem last year. When my providers sent a tech to set up a new connection, he asked me if I wanted to personalize its name. He said "some people like to call theirs FBI van or something."
At the same place one of my neighbors had FBI van, too.
It's just a silly thing some people like to do. 👌🏼
Interesting, I've never encountered that before!
