What’s the origin of this phrase?
The Word Detective offers up some explanation about airplanes. I don’t use the expression mainly because it just doesn’t sound like it fits the context of the sentence. Now that I see this goofy airplane explanation, I feel vindicated.
The only other explanation I have seen also relates to 1940s RAF slang. It was supposedly an ironic allusion to the remodelled shape of an aircraft after it had crashed nose-first into the ground.
WAG: You marry her when she’s 21, slim waisted and top heavy… 20 years later…‘Everything’s gone pear shaped’
Thanks for the Word Detective link; I didn’t think to try there, but I should have. That may be the best I’m going to get.
Thanks, all,
RR
there is a very similar thread that you have posted recently:
Hmmm…would a courgette gone pear-shaped be a butternut squash?
