This episode explains a humorous expression for someone who looks pleased with themselves while appearing to have done something they should not have done—or to be keeping a secret. It also introduces “smug” and “coy.” The key nuance is that ordinary pride in an honest achievement does not fit the expression.

Cultural note: The idiom can sound teasing or accusatory because it suggests guilt, secrecy, or self-satisfaction. Use it only when the relationship and context make the joke welcome; it is not a neutral way to congratulate someone.

Keep exploringA smile can signal honest pride—or suggest someone is hiding a mischievous secret. Context makes the difference.
