I did corporate training for an international company for about 20 years. Once when I was in Mexico something happened in class and I said something was okay and used my finger and thumb to make the okay sign. They kind of laughed and started talking among themselves. I guess the okay sign means asshole in Mexico so when they explained that I laughed with them and said I didn’t know that. One of the jokers in class said “yeah, okay we believe you” and gave me the okay sign. lol
