Kackin it (Also Kacking and Cacking) Is a word used to refer to the highest state of laughter. Kackin it is when you have laughed so much you have surpassed crying ,urination or any other bowl movements. Once in the state of Kackin it one has little self control and may have to be left alone to calm down. Kackin it can be potentially dangerous, but is often a sense of great ecstasy.
