look up any word, like ratchet:
One who mocks his or her mother, often by teasing or imitating her.
Mom: "OOh, Hurry! I don't want to miss 'Dancing with the Stars'!"

CHild: "Oh, no..missing 'Dancing with the Stars' would be tragic. Let's hurry, hurry, hurry--quick as a furry bunny!"

Mom: "Stop being such a mother mocker! It is a good show!"
