When you have to take a shit, but it's a very painful, spiky one, a reference to the Spiky Hair of Makoto Naegi
Person 1: "yo man, I had the most painful shit, man"
Person 2: "yo, dude, you just had a Makoto Dump"

Its called a "rolling dump" when you take a shit in your car, and put it in newspaper/mcdonalds mapkins/mc flurry cup, whatever you have handy, then set it down under your car tire at a red light. When the light turns green, you win!
