"Shirty" describes someone who is easily annoyed or bad-tempered. Think of it as someone who woke up on the wrong side of the bed every day 😠. It’s a British slang term, so you might hear it more often in UK shows. Unlike outright anger, shirty-ness is more like a constant low-level grumbling. Imagine a cat that's always hissing but never actually attacking. It can make them unpleasant to be around, even if they aren't being directly aggressive.
