빈정대다 - ridicule someone 비꼬다 - be sarcastic Don't ridicule me! --> 빈정대지 마라! Don't be sarcastic! --> 비꼬지마! I hope this will help you. : )

The right word form would be 빈정대지마 or 빈정거리지마. The meaning is more or less the same. But 비꼬지마 has stronger feeling and objection. The meaning itself is not so different. 화이팅 :)
