To hang up on someone without saying goodbye, in the manner of Jack Bauer on the show 24. To Bauer someone usually simply means to end a call abruptly, since you're way too cool to say goodbye to people.
Dude, I was getting off the phone with Rick, when he totally bauer'd me! What's with that?

To be killed. Deadly. Dead. Fucked.
