A term used to describe the process of inserting dehydrated fruit (esp. apples) into someone's anus, and then giving that person an enema, as to cause the fruit to expand (like popcorn kernels expanding as they are cooked).
If you don't stop talking about Abraham Lincoln all the time, I'm totally going to popcorn kernel you in your sleep.
