Growing up, I always called them jimmies, because that’s what my dad, who was born and raised in Boston, called them.
I only realized that wasn’t a term everyone knew about recently, when I said it to a co-worker and they had no idea what I meant. After looking it up online, I found out that what I’d always called them was a regional peculiarity I’d picked up even though I never lived in the region it’s used in, and that there are several other terms used for them as well.
So; what do you call them?
