It nicely illustrates what we can call, "Malapropisms that are maybe even better than the correct word or phrase."
Here's the definition:
To accept an unpleasant or difficult situation because there is nothing you can do to improve it. I don't want to spend the whole weekend working but I guess I'll just have to grin and bear it.
But the idea of getting naked makes whatever unpleasantness you're talking about that much more uncomfortable. Unless you're a nudist.
