na'vi and curses

[MarkD]

I wonder if the na'vi do this?

For example look at this hilarious commercial someone posted http://www.youtube.com/watch?v=JahdnOQ9XCA

lol I have never seen that before!

I wouldnt be surprised if the Na'vi have some sort of curses, maybe we will see in the upcoming releases!
