Super weird one. Produce bags from the grocery store are called "gnome bags."
Years ago, we found out that Walmart does not mind if you just take a whole roll of those bags. We use them instead of zip locks, sandwich baggies, Saran wrap, and dog poo bags. They became "gnome" bags because we had an old toilet paper roll holder in the shape of a gnome that we hung up to hold the roll of bags, and we all just started calling them gnome bags until it got to the point where we'll occasionally say it in public accidently. Lol.
