I learned this game in English.?? It can work with any topic.
Here's how this works.?? One person has to come up with a list of 5. words that pop into their head as fast as they can.?? Then, on the same post, 5 avatar related words that pop into their head.?? The next person then has to try to make a sentence with these words without adding too many extras.?? On the same post, they think of 10 new words for their next victim.?? Here's an example
1.That
2.Cow
3.Dirt
4.Old
5.Yellow
1.Aang
2.Boom
3.Rock
4.Smash
5.Fire
**Next person**
Aang smashed that old yellow cow in the dirt with a rock.?? Haha.?? That turned out pretty good.?? I would then list 10 new words on the same post as my sentence.?? Have fun!
