Internet slang contraction for "All of them, Katie," a play on the phrase eventually spoken by then-Vice Presidential candidate Sarah Palin, after a very long pause, in answer to a question posed by then-CBS Evening News anchor Katie Couric regarding what newspapers and magazines Palin had read before being named as the 2008 GOP Vice Presidential nominee.

Can also be used with a comma: AOT,K.

The contraction is been used in a number of ways, but most specifically:

1. To convey a vacuousness, or general lack of thought or intelligence
2. As an all-inclusive, or "all of the above," especially to questions of ignorance, arrogance or blind faith
