Welcome to Showderp. Here, someone with a tripcode becomes "champ", and 6 anons SHIT on the thread to give him new crappy pokémon (such as a living pile of purple sludge, a trash bag, a floating gassy tumor, a vore purple goop, etc) to use in the Pokémon Showdown ladder. The anons on the thread will join the battle and hilarity will ensue because FUNNY POOP.
When champ is tired of the scat, he can ask for either a new batch of shit sets or a new champ. When a new champ is called, someone else can post with a tripcode to champ and be given new stinky diarrhea, and the cycle starts once again.
If you still don't understand, please read our rules below or I will personally pull my short shorts down and shit on your face. It would be funny, haha.
