Regardless of what part he’s nipping, nibbling, or gnawing at, we’ve had just about enough of it. Enter cabin fever.
Disclaimer: The above link will not take you to a Wikipedia discourse on the history of cabin fever, a term first recorded in 1918, but to the IMDb coverage of a 2002 movie by this name about five 20-somethings in a cabin in the woods who “fall victim to a horrifying flesh-eating virus, which attracts the unwanted attention of the homicidal locals.”
Given a choice, I’d go virus. But I just don’t think I’m going to see this fine work, much as I like the poster.
