A mixed drink created by mixing Nesquik with a nip of Baileys, preferably in the Nesquik bottle itself. Named for the notoriously crime ridden Dorchester neighborhood in Boston, the original home of the drink.
The cops have been cracking down on public drinking, so I've had to start subtley pounding back Dorchester Mudslides. Looks like Nesquik, tastes almost as good.

Upon completion of the defication ritual, a Tuscan Mudslide is the experience of having a tenacious amount of poop residue left on the anus, thus having to wipe a tremendous amount until the buttocks has used up a weeks ration of toilet paper.
"After his big sticky dump, Joel was telling Curtis about how much his anus was bleeding after he was done wiping. Curtis knew that Joel had just experienced a Tuscan Mudslide."

"It was as if I was just wiping a piece of toilet paper across a brown sharpie. That was a rough Tuscan Mudslide."
