First you Marinate...that's when you feel a little something in your stomach, but you know you aren't ready yet. Second you Percolate, that is when you hear "percolation" in your stomach...almost like something in boiling in there. Last but not least, Evacuation....that is when the feces exits your body, the complete process of this is known as MPE.
