What is the origin of “stroppy” (meaning annoyed and obstinate, if it’s a Rightpondian expression) and its derivative “strop” (noun, as in “having a strop” and verb, meaning “being stroppy").
To my surprise it’s an abbreviated form of obstreperous. First cite in OED is this one:
1951 H. Hastings Seagulls over Sorrento ii. i, in Plays of Year IV. 76 There ain’t nothing clever about answering him back and being stroppy.
The back-formation strop (no relation to strop meaning strip or band) has an earliest cite of 1970.
Definitely Rightpondian, by the way.
Notice the OED has a ? before “obstreperous”.
Thanks, Eliza, I missed that.
