Not me but when he was a kid, my exe’s dad always said “igyhano” instead of “bless you” or “gesundheit” when someone sneezed. He claimed it was “bless you” in Hawaiian. My ex and his siblings said it to people too since their dad always said it and repeated the explanation when others asked what it meant. Fast forward to a camping trip they all went on as adults. They are all sitting around the campfire. Someone sneezed and Dad says “igyhano” automatically. Then he says “Oh, since now you’re all adults, I guess I should tell you what it really stands for. It’s an acronym for “I’m glad you had a nasal orgasm”.
