Massive, putrid, uncontrollable diarrhea which strikes after eating McDonald's fast-food.

Usually strikes when you are the furthest away from a toilet. Being mostly liquid, there is no holding back Ronald's Revenge. The quicker you waddle, the tighter you clench, the faster it comes out.
If you eat McDonald's you better wear your Depends.
Goes down good, then comes Ronald's Revenge!
