I just used nRFConnect and found a device name that was strange to me. Got curious and asked Google.

A personal pleasure toy (aka sex toy) that is visible on Bluetooth. Just for fun I walked a bit around in the garden and found the direction where the signal got stronger.

I can now deduce with reasonable certainty which of my neighbors home has a remote controlled sex toy in it. As I know the family living there and how conservative they are with their cultural background I would not have expected that.

Imagine how I now just could now wait for the parents to make their big yearly holiday. From the website of the tool I know the specs on how long the battery holds when not in use. So if before the end of the holiday the tool is visible in Bluetooth I could reason with a very high degree of certainty that it was the daughter's tool. If it were so this tool would five her away. It would be a liability for her (if it is her tool). If their community knew, they would be appalled. So it is a liability for the whole family as well.

They are nowhere near the technical ability to identify this liability I just stumbled upon by chance.
