Blue-spoof means causing someone to believe you are speaking to them while actually using the hands-free device for your cell phone, or believing someone is talking to you, but they're using their blue-tooth. (Source: merriam-webster.com)

Blue-spoof指你用蓝牙耳机在打电话时，别人误以为你在跟他说话；或是别人用蓝牙打电话时，你误以为人家在跟你说话。我们称之为“蓝牙误会”。

For example:

I was blue-spoofed by Tom while he was talking to Barb on the phone.

汤姆用蓝牙跟巴伯打电话时，我以为他跟我说话呢。
