1.
A stock expression from the vocabulary of baseball slang. The 'high hard one' is a fastball pitch delivered high in or above the strike zone - an intimidating pitch because of its speed and proximity to the batter's face and head. By extension, anything frightening or painful.
"I'm through playing around now. Let's see how he likes the high hard one."
