Innocent Swearing

When someone uses a naughty word without realizing it's a naughty word. Quite often, the person (almost always a child) will get into a lot of trouble for using such a bad word without knowing the meaning of the word or what he or she has done wrong.

Literature

 * The novel My Best Fiend had one chapter where the headmistress was cracking down on swearing at the school. When the main character's friend fell and got a nasty gash on her leg, and all the other kids were crowding around, she shouted: "She can't move her bloody leg!" A variant, since she did know "bloody" was a swear, but that wasn't what she meant; she meant the leg was covered in blood. She explained this to the headmistress, who agreed that it was a shame perfectly good words became swears.
