The most accurate description of an absurd situation in which everything must be taken seriously to the point of incredibly non-treathening incomprehension.
Bob: "We must commence this battle by vigorously shaking our booty"
Tom: "Nani the fuck?"
Nana of the Pat is a Brazilian street slang word best known for describing someone with an abnormally deep voice as well as grey short hair. If you ever come across someone that comes under this description, DO NOT START A CONVERSATION AT ALL COSTS.
OH MY GOD THAT WOMEN WITH SHORT GREY HAIR AND AN ABNORMALLY DEEP VOICE IS SUCH A "NANA OF THE PAT" SHE TALKED TO ME FOR SO LONG THAT I MISSED MY LIZARDS FUNERAL.
