Which is correct?
- “get upset”
- “pitch a fit”
I’ve always used “get upset”. Not that I remember my parents using either, but I’ve certainly used “get upset” with my kids when they were little. In fact, I don’t ever remember anyone saying (out loud) “pitch a fit”.

On the most recent episode of “Judge John Hodgman”, they bring up a good point that people in the South (literally where I’m writing this from) say the word get as “git”. That’s a generalization, to be sure, but I can understand it. Pronouncing it “git” is the least of the Southern drawl-isms I’ve heard around here.
(My personal favorite is “dern” instead of “darn”.)
Anyway, I think the “get upset” is the correct finish to this phrase. And I will hear no more about it. Case closed.
