Care Bear Stare

O_O (and variations thereupon) are referred to as the Care Bear Stare. The O_O catch phrase came into existence during The Haunted Broadsword Cares episode of NSFW in which the chat room posted it in response to YouTube videos where people were ranting about pointless things.

Origin of Care Bear Stare

The Care Bear Stare is a reference to the super power of the Care Bears. When they activated their power, they would say "Care Bear stare!" (or "Care Cousin stare!") and a beam of light with their individual symbols would come from their chests.

Yeah, it's a very lame super power.
