What does pre-scratch and post-scratch mean? Or when people say "Pre-scratch kids" or "Post-scratch kids", what do they mean? Also what's Auspistices? I've read about what it meant before but I was still left in confusion.

Pre-scratch kids are John, Jade, Rose, and Dave. Post-scratch kids are Jane, Jake, Roxy, and Dirk. Pre-scratch and post-scratch are terms for the B1 universe and B2 universe. B1 universe is where John and his friends are kids and play sburb. B2 universe is where Jane and her friends are kids and play sburb. An auspistice is a troll that prevents two other trolls from entering a kismessisstude and stabilizes their relationship.
