Forgive my sin of not Social Distancing last night, but I was with group of friends and I said “Ass over Teakettle” in an anecdote I was telling. I believe it is an expression I picked up from my parents who are from New England.
No one at the gathering had heard that expression, and I have used it for most of my 60 years on Earth. FWIW I live in Missouri, but I grew up in the Northeast (New England and upstate NY)
Ass over Teakettle = Klutzy Fall
Have you heard the expression before, and where did you hear it?
