Don't feel bad, my aunt had thing happen, she believed she had two female kittens and took them to be spayed.

Turned out Milly was really a Max. Aunt was rather offended. She only wanted female cats. (Aunt has lots of ... ideas about really weird things.)

Decades ago I went to Spanish camp. One of the American female counselors accused one of the male South American counselors of being a Latin Lover, only interested in flirting.

He vociferously denied that, stating that he was not a "cabrón" whose only aim was to chase women, he had come to the States to study.

My brain went "cabrón" = "stud/flirt".

Went back to school and the guy in front of me had heard I met a cute guy at camp and started giving me flack. Knowing of my classmate's reputation as a ladies' man, I responded by saying, "Ay, Miguel, qué cabrón eres!"

Spanish teacher was in front of us. Did an actual spit-take and yelled at me.

And that is the story of how I learned that words could have different meanings in different countries and that I had learned my first swear word in Spanish.

BTW, 'Miguel' was not a very bright boy and never did figure out what I had called him because the classroom dictionary had it listed as "buck".
