bluetooth crazy

1. The state of appearing insane to people who can't see your wireless headset for your cell phone.

2. Someone that you think is insane until you see their bluetooth headset and realize they're just a douche bag.

Dude:"Did you see that crazy guy talking to himself on the corner?"
Chick:"Oh, that was Bob. He's on a conference call. He's just bluetooth crazy."
Dude:"What a douche bag."
