There's a Budweiser commercial that talks about a combination foam number one finger and beer holder. They call it a "foozie," a combination of foam and coozie.
But here's the thing. "Coozie" is a variant pronunciation of the word "cooze," which we all know is:
–noun Slang: Vulgar. vagina.
But that's not all. I asked my mom's boyfriend what he calls a foam beer holder. "Oh, well I call it a 'coolie'."
–noun Offensive. an unskilled laborer, esp. formerly in China and India.'
The word is cozy. Ok? It's a beer cozy. Like a tea cozy, but for beer.
