pettish

/ˈpɛdɪʃ/

If you stomp your foot angrily when the bakery is out of your favorite cupcake flavor, you're acting pettish, or like a little kid who's in a cranky mood.

If you do nothing but complain in the emails you write your grandparents — about the weather, your friends, your family, and what you had for lunch — they may think of you as pettish. Pettish people are irritable and petulant. Some word experts believe there's a connection between the adjective pettish and being a pet, or a spoiled child.
