Ok, so rulez are very simpleton. You have to create a sentence and every word have to start with the same letter in the post above. To make it more fun try to type the longest sentence possible, between 5-12 words. Remember to provide a letter for the next shitposter to make a sentence. You can make up words if it turns very hard.
