A 'bitternut' refers to the nut of the bitternut hickory tree, known for its extremely bitter taste. These nuts are not typically eaten by humans due to their unpalatable flavor. The bitternut hickory is a common tree in eastern North America. The term highlights the defining characteristic of the nut โ its intense bitterness. Think of it as the opposite of a sweet treat; it's a sharp, unpleasant surprise.
