Raintard

Acting like a combination of Rainman (Dustin Hoffman) and a Retard joined together.

Kayne is such a Raintard

or

did you see that guy Joe, he is acting like a complete raintard

Emma always says when you act like a rainman, you are a really a raintard, and they always think its their cousin fault!
