adjective
stroppy
STRAH-pee/ˈstrɑːpi/
Bad-tempered and difficult to deal with.

Etymology
Stroppy is recorded as British nautical slang meaning “rebellious,” perhaps a slang reshaping of obstreperous. That possible source connects noisy opposition with the broader sense of resisting control or advice.
In context
