When you have acute pain in the stomach side due to explosive diarrhea. Holding the diarrhea inside will make it feel as though a ram has stabbed your side with it's horns (either side). It should be painful and unrelenting, just like the full force of a ram's stab.
Yesterday I ate a Double Down on KFC and .... oh boy... I feel the ram's stab!!! I'll be right back....
