KFC Regret is the term used to describe the feeling one has after eating KFC (Kentucky Fried Chicken).

One sees a nice looking burger or Popcorn Chicken and thinks that it would be a good idea but once consumed has a feeling that one's gastric tract is lined with grease.
"I thought I would have a big KFC burger but now that I've had it I am having KFC Regret".
