@wildweasel it is my understanding that it is "Jerry rigged" from world war ii usage referring to Germans as Jerry's? and their equipment being slapdash?
but to be honest as I write this it suddenly sounds super made up and I'm filled with doubt???
@earthshaking Oh, shoot, forgot to paste that article. https://www.merriam-webster.com/grammar/jerry-built-vs-jury-rigged-vs-jerry-rigged-usage-history
@wildweasel Ah, I saw that my friend effika linked that to you earlier, yep. It was a more complex of an evolution than i thought!
