false anger
The kind of anger you get when you're mad at something that, when thought out, is nothing to be mad at at all. Usually caused by lack of sleep or previous anger that day.
Ray was furious at Troy because Ray came downstairs to read, and Troy had the TV on, which was very distracting. (Ray has false anger and not regular anger because he came to the room with the TV on already, and he could have gone anywhere else to read.)
