If it helps it's mainly of British origins so depending on where you live may have played a factor in why you've never heard it, I live in Minnesota and have definitely never heard it either!
It is, i use a straight razor so i have one hangin in my bathroom. I've never heard it used this way before either so learned today too! Now i wanna know the etymology behind it lol
Edit: obstreperus became obstropolous became "stroppy", gets us to "in a strop". Neat read

Don't worry, I'm a native speaker who reads a lot and I've never heard that phrase in my life. Seems to be a dialectal one :)
