The slang word for Blue Tooth. A small wireless device allowing people (mostly douches) to communicate on cell phones 24/7, making it look like they are talking to themselves. These people think they are awesome because they are so nifty with their headsets. But they are just douches.

4.
A douchebag walking around with a bluetooth head set on. Most likely having a conversation way too loud as he looks at you funny for listening to his phone call.
This guy walked up and starting talking to me. I responded but then he just stared at me and got upset that I was interrupting his call. Turns out he was on his douche-tooth.

As Joe got out of his yellow hummer he made sure to put his Douche Tooth in his ear so that everyone would know what an important bad ass he is.
