The idea of this is to start a new word that begins from the last letter of the previous word. Example (not putting Avatar for an example so not to give any idea away):
Dog
Goat
Tiger
If you think people may have trouble guessing why the word you put is related to Avatar, tell them why. Example:
wolf (the lone wolf mentioned in Bato of the Water Tribe)
I say this because on a Friends thread, I put homosexuality and a person told me hat there is so being gay on Friends, then some other people started defending me saying stuff like Carol/Susan, first impression of Chandler, and I said that all of the friends have acted gay at least once, then someone put down another word that started with an H, and since that would have caused the whole thread to be an argument, I p0ut down another H word and it went on.
Okay, first word is:
