大街上有人迎面走來，嘴里還振振有詞地說著什么，大家紛紛側目，覺得他很奇怪，其實，人家只是在用藍牙耳機打電話而已。現在，隨著藍牙耳機的普及，這樣的誤會也慢慢少了。不過有時候熟人在一起還是難免誤會。

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指你用藍牙耳機在打電話時，別人誤以為你在跟他說話；或是別人用藍牙打電話時，你誤以為人家在跟你說話。我們稱之為“藍牙誤會”。

For example:

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

湯姆用藍牙跟巴伯打電話時，我以為他跟我說話呢。
