A name for a retard with autism. This name can also be used in situations when you just want someone to go away. For example: The special kid is asking you to get him a juice box. You say, SHUT UP RETARDOAUTIST. He will go REEEEEE MOMMY WHERES MY CHEETO IPAD and then just run away to break another wall. Problem solved :)
Timmy is such a retardoautist. He plays minecraft and clash royale on his Cheeto IPad! Oh no! He just spilled HI-C on his moms phone. It will be pretty hard to clean that off.
