Once at my grandmother's house I was wheeling around a baby doll and kept telling my older brother to try and take it from me, each time he did I smacked his arm and shouted, "GET OFF HIM YOU BASTARD!" not knowing what it meant, grandmom set me straight...
Another one of these stories goes for my cousin. I was in the car with my cousins and my aunt, one of the girls was my age and her brother was a little younger. Out of the blue she hugged him and said, "YOU BASTARD!" she mistook it as a compliment and my mother never looked so stunned (until a few years afterward.)
