Loser takes a shower using custard instead of soap
Gems loses
Next - loser provides list of minimum 5 items to winner and rough clothing options, winner decides how loser gets messy/wet with them and what loser wears
Seeing as you didn't post "im in" I summarily rule that you john Smith lose this round and carry out the forfeit.
Next dare.
Loser will submit themselves as the defendant to a court of mess style punishment thread for a week presided over by a judge (the winner or winners choice to be judge) and get messy (respecting their limits for items used of course)
