The father of my girl friends son came by the other evening to pick the boy up, I answer the door, we exchange greeting. He looked at my kilt, turned away, then looked back again so fast I thought his head would roll from his shoulders. After staring for a long moment I told him it's a kilt, he looked up smiled and said thats great its not what I thought it was.

He had heard the word "Kilt" and knew it to be Irish or Scottish or something like that, but had never seen one.

Which leads me to believe. At least some of the people that call a kilt a skirt, just don't know better.
