I/S 

The I/S is a chat board on Noepets in which stands for “Idea/Suggestion”. Its pretty much the chillest board there is, and everyone there is pretty mellow. There are around Three classes on the I/S. The first class consists of The King and Queen, Walker and Fluffy, and then there are Sess, Allie, Alex, Lauren, Pavel, Stevo, Chibi, Zaf, Freddy, Nora, Aly, Bridget, Reese, Star, Kace, Marina, Fwee, and Misti. The second class citizens are as followed: David, Mindy, Dessy, Luke, Teagues, All the Gabys, Mustang, and a bunch of others that I don’t really care to name. The third class is just everyone else who comes on. The current I/S couples are Walker and Allie who will be getting married soon and Lauren and Alex!!! The I/S is a pretty cool place to be, when you know your ways around the boards. If you go down the wrong street, you can fall into an alley way and get beat up, don’t you know. Your pretty hot stuff if you’re accepted into the first class of the I/S!

sess: hey sup i/s ur king is speaking
Walker: No, I don't think i was speaking!
