This is definitely one of those expressions that needs to be taken seriously and with the true roots in mind. It is not an expression that can change to suit OUR time. (Using the expression = bad, knowing it and philosophizing about it = good)

A formal definition: "a concealed motive or unknown factor affecting a situation in an adverse way." Or simply: "something suspicious or wrong."

Add this: Quite possibly during the Underground Railroad, assuming we're together on this that it was a good thing to help free slaves, a "nigger in the woodpile" was a good because they were in a hiding place because bad folks were about- There's no need to hide if all around were good people, supporting the Underground Railroad and its sympathizers!!! Soooooo, better to be in the woodpile than shackles! ...this complicates the meaning of the term, but good to think about.
Classic meaning: "Ever since the new boss has been here we've not known much about the company's restructuring, he's a nigger in the woodpile, I hope I'm not about to get fired!"

My theoretical meaning: "The new boss is a fucking asshole, I'm glad the human resource person is full of integrity, I know those of us who are good workers will be fine- we're like niggers in a woodpile around that asshole."

This metaphor refers to the solution to a puzzling problem. The context is that a hiding black slave would blend into the woodpile and wouldn't be noticed at first glance.

Basketball Coach: Well, they seem to know all of our plays. Let's have "Too Tall" run the #2 pick and roll with "Tiny"
Team Captain: Damn, we've practised all season, no we're finally gonna use the nigger in the woodpile.
2. I've seen the flop, the bend, and the river, and i like my pocket 10's, but something tells me he's got niggers in the woodpile...I fold.
