Fastidiot 

Noun

One who is - at the same time - fastidious and idiotic. A Fastidiot will demonstrate a meticulous, sensitive, or even demanding attitude, paying great attention to even the most minute details, while concurrently displaying the idiotic tendencies of a person with a remarkably low intellect and with a poor (even horrendous) capacity for decision-making. Fastidiotic behavior is often demonstrated by individuals exhibiting signs of Stolevrusny.
My buddy Stole is the biggest Fastidiot on the planet. He is a highly-successful professional, he eats healthy and stays super-fit. His car, home and office are all meticulously clean and people joke that he lives an almost monastic existence. And then, every f-ing weekend the guy takes some insane off-ramp straight into the abyss, making decisions as if he is a homeless guy living on the street with no consequences for his actions.
