Know someone who always seems annoyed, grumpy, cranky, or irritated? That person is peevish. Some people are peevish in general, but most people can be peevish about certain subjects — we all have a pet peeve. Lots of people get peevish about language: like using the word like all the time as verbal filler. Being peevish is almost always considered a form of pettiness — it's not a good thing. When you're peevish, you're not really looking at the big picture.
