What is Awesome-o?
1.
Refers to an episode of South Park where Cartman dresses up in cardboard to become AWESOME-O, Butters' new robot friend from Japan. Of course, Cartman is only doing this so that he can learn some of Butters' dirty secrets.
The inspiration for the name comes from Honda's ASIMO humanoid robot.
