Last night, while watching the band Attention Class at the Rendezvous, the singer mentioned that they had had merch for sale, including $3 beer cozies. Except he said COO-zies. Beer COOZIES. Then the band's keyboardist/flutist/xylophone player said "It's okay if you call them CO-zies."
After a short argument of which is right—co-zy or coo-zy—they took a vote of the audience and the overwhelming majority of the people in the room agreed that those little foam beer can holder thingys are, in fact, pronounced beer coozies.
What are you people, Canadian? They're cozies! CO-ZIES. Because they're like a cozy little holder for your beer!
