Probably the wifi name of his cell phone.
That’s a pretty clever thing I’m going to have to play around with.
In 2009 I was working in a branch office in a very liberal city. I took an old WiFi router and locked it down so that no one could connect to it (except Ethernet) and changed the SSID to something very derogatory regarding prezzy stompyfoot. Then I placed it in the window so that every business (including the city hall across the street) could “see” it.
It took two weeks before someone saw, complained, and our network boys started looking for it. The never found it.
