Language can be interesting - especially slang and local expressions.
I had a customer a few years ago who came in and was obviously British. He was looking a little distressed and asked for rain gear and motioned for lowers. It took a second for me to say "Oh rain trousers" his relief showed immediately and he replied, "yes, yes, rain trousers."
He went on to say how the word "pants" was a difficult thing for him. In Britain, pants are underwear. He had a hard time with that apparently and told me the horror he felt the first time he went golfing and his golf buddy asked what color pants he was wearing......it took him a minute to translate.
We used to have a local expression here that came from the SCTV television show - The Schmenge Brothers Polka Band (John Candy and Gene Levey) shortened to just Schmenge, slang for cannabis.
