a person who uses their blue tooth headset when unnecessary, or leaves attached in ear when not having a conversation.

A person who walks around with their blue tooth on and has extremely loud conversations in public, seemingly enjoying sharing their business with strangers.

A condescending asshole who goes everyhwhere with their blue tooth head piece on, even when quite inappropriate. They are always speaking vociferously with no regard for others around them.

Someone who is a total tool, but you cannot refer to them as a tool because they are your "friend" or you are related to them.
