When you get diarrhea in waves, and you just sit on the toilet alternating between shitting and wiping, thus building layers of shit and toilet paper akin to a lasagna. (Liquid shit, followed by a layer of toilet paper, followed by another layer of liquid shit, then another layer of toilet paper, etc.)
Oh man! I ate some bad Mexican food last night that left me sitting on the toilet making a diarrhea lasagna for an hour.
