a prolonged outburst of hissing by a cat.
Tweety, my late calico cat, constantly hissed at the other cats in the house. We called her Madame Hissy Fit as a result.

Get the hissy fit mug.
A term coined by mothers describing the hysterical (hissy fit) reaction of their little children when mothers say no to buying toys in a department store
Meredith and Little Jamica are in Harrods in London

Little Jamica: Mommy, look at this new stuffed bear!

Meredith: Oh, it's cute! Oh wait, too pricey, honey. So no, don't even think of buying it.
Little Jamica: WHAT?!! NOOOOOOOO!!! WAAAAH!
Meredith: Oh boy, here we go again. One more department-store hissy fit.
