A below average kid who is coddled and rewarded for mediocrity, usually by an overprotective mother, a 'sensitive' dad, or the public education system. The term stems from the concept that, like a snowflake, all children are special and unique and thus they should be treasured just the way they are so as to build their self-esteem.
Deanna's special little snowflake is in for a rude awakening when he gets out into the real world.
