My first days in the US, vistited my aunt in NJ. We went to a supermarket, and at one point I wanted to draw auntie's attention to some product so I called out: ciocia! A few heads turned in what looked like disgust. Well, they were Hispanics and in Spanish slang "chocha" is not such a nice word for vagina.
Your story is so much nicer than mine and it is so much milder.
I learned not to say ciocia at an early age in my community. We have a big Puerto Rican community where I live. All I can say the burn from being slapped by an elderly Puerto Rican lady is still felt today. Just recently I got into an arugement with a lady at Wal-Mart for she heard the word ciocia while I was speaking to my son in Polish. She had to add her two cents stating that I am teaching my son bad words and degrading myself. Ciocia (chocha in Puerto Rican) means p***y. Go figure!
