Nigger in the woodpile American old-fashioned noun phrase

If you describe someone as shifty-looking, they seem dishonest, untrustworthy, or suspicious.
To distrust someone.
This phrase dates back to the 1840s and 1850s when the Underground Railroad was at its peak. The phrase is thought to have originated from actual cases of escaped slaves being hidden behind piles of firewood during their journey north.
Another possible source for the phrase is the practice of transporting pulpwood on special railroad carts with an exterior frame and the wood packed within in quite neat rows and stacks. It was possible to smuggle people into the pile itself due to the nature of the cars.
To be very wet
Because of forgetting bringing an umbrella, I look like a drowned rat when it rains.
