Actually, it means “open”, as in ordering something (like a door) to open. It is an Arabic word. So, when you say “Open, Sesame”, you are really saying, “open open”!
The first time I did laundry in a new house, i miscounted the steps to the basement, fell, and broke my ankle. I got off easy, I guess. Never understood why laundry is put anywhere other than the same level as bedrooms and closets.
Oooooh, my Mini-Cooper would love that!
