What does it mean to simper?

To simper means to smirk or smile in a silly, self-conscious, or affected manner. This term often conveys a sense of insincerity or an attempt to appear more appealing or cute, typically lacking genuine joy or earnestness. In many contexts, simpering can suggest a degree of naiveté or an overly coy demeanor.

The options involving laughing joyfully, frowning slightly, or responding cheerfully do not capture the nuanced connotation of simpering, which is more about a specific type of superficial smile rather than genuine emotion or expression. Therefore, the correct answer accurately reflects the essence of a simper as a contrived or foolish smile.
