Politician Poop
A dump where your colon, and subsequently, the majority of your toilet are full of shit like a politician. This bowel movement is the result of a fiber rich diet, and is noted by several productive pushes, an overuse of toilet paper, and the need to flush more than once to get rid of the mess.
"I'm sorry I'm late. I had to take a politician poop, and it took twenty minutes to flush it all down."
