Oh, those cheese grinders!

An artist exhibiting at Brookside shared a conversation she'd had with a woman at the Saratoga Art Center:

Woman: We really only publicize our events in Saratoga Springs...we don't want the Galway cheese grinders to show up!

Patty: Cheese grinders?

Woman: Oh, you know, people who accidentally drop cheese on the floor at parties and then grind it into the carpet with their heels.

Patty: I'm from Galway....

(For those who don't know, Galway is a small, rural-ish town near Saratoga.)
I've totally never heard this insult before but I love it!!!
