flintiest
Coldest in demeanor
Flintiest is the superlative form of flinty, meaning the most hard, unyielding, or emotionally cold.
A flinty person shows no softness or sympathy; the flintiest among them is the most severe: She had the flintiest stare I'd ever encountered.
The word derives from flint, a hard stone that resists pressure.
