When you find you have a tapeworm infestation after using the toilet. Instead of a normal lincoln logsets... you see a pile of bloody tapeworms with little poop nuggets that look like meatballs... thus, a spaghetti surprise.
My friend Matt just got back from Mexico and had to go to the hospital after having a spaghetti surprise in the toiler.
