A nicer way of saying, Kiss My A_s, used in the southern USA. Grits are food and something we eat, not between our toes like one person said. Gritty dirt is between your toes, but not grits. People in the south say "Kiss My Grits" jokingly, not in a mean spirit. And lastly, "Kiss My Grits" is not meant to be anything related to a racial saying. It's just a silly fun southern saying.
