I had a co-worker who had the unique talent of being able to perfectly express her discontent with her job. One day she was storming around the office after being reprimanded for something she viewed as insignificant. She passed me in the hall, glared at me and said, "Yeah, I have a bad attitude. And, I don't give a shit."
I ask you. Is that the perfect definition of "bad attitude" or what? Of course, I never knew if she didn't give a shit that she had a bad attitude or if she just generally didn't give a shit.
