One who keeps himself or his aims hidden. Keeping things secret, or concealed even seemingly pointless secrets they can be referred to as a dark horse when the interest, relationship, or action is revealed. Perhaps surprising, unexpected, even vaguely scandalous.
"Did you hear Dick won a mountain biking race?"
"Wow! What a dark horse, I thought he was a couch potato!!!"
"Trent has a new hot younger girlfriend, they were keeping it secret because he's her dad's friend"
"What a dark horse!!!"

Get the Dark Gingermug. A rather descriptive term for depression.
Refers to how it has never been fully understood after centuries, how it truly reaches depths beyond description, and how it lurks among human beings without any regard for success, social status, abundance of friends, or nobility of spirit.
Also hints at its attitude for invisibility beyond the confines of one's mind. Even your best friend could be living in a world of pain, yet it might be impossible for you to even suspect it.
It is, in many ways, the only source of death that remains truly unexplained.
Term from Italian (il male oscuro).
