A medical term referring to the innermost part of the anus, and possibly the most important part of the anus. While the exact root of the word is unknown most believe it comes from the Greek 'kananakookus rutulis dennis'.
"Did you hear that during the filming of Brokeback Mountain an actor suffered from a ruptured kananakook?"
