Is a way of saying diarrhoea or violent shitting. The shits involves sitting on the toilet pan and basically shitting out your guts in liquid form. It's like pissing shit out your anus in other words. The shits is not a very pleasant experience unless your a complete shit loving wierdo who enjoys urinating brown liquid out of his/her ass. The shits has many different causes. One of them is by eating food with a very hot pepper sauce on it. After eating extremely spicy food, the explosive diarrhoea experience is even worse than usual. The inside of the ass cheeks burn something awful and it is like someone has shoved a flame thrower up your rectum and pressed the trigger. The shits can also be caused by food poisoning (eating something that is not cooked properly). In this case vomiting may also happen.
