"Bluetooth" is the official noun for a specific wireless connection, where you connect devices within a short range. Apparently, the term "Bluetooth" comes from a King called "Harald Bluetooth", who united Denmark and Norway- the same way a "Bluetooth" connection "unites" devices and connections. Ex: I often forget my earphones are connected to my phone via Bluetooth. So, sometimes I wander too far away from my phone, and the music stops. Ex: John, you can send the photos via Bluetooth!
