When I was around five years old, my cousin who is one year older than me came to visit. We were putting on our gear so we could go play in the winter snow. He was putting on his hat, it was one of those hats like a cap with a little pom-pom on top. I asked him what he was doing and he said, "putting on my buttocks." For the longest time after that I thought that the type of hat with a pom-pom was called a buttocks, and referred to it that way.
