Nuts Up

When I noticed this subway poster last week the "nut up" part threw me, I kept thinking it had something to do with squirrels, wondering what squirrels and their nuts might have to do with zombies. A reliable source explained to me that I had it all wrong, it has nothing to do with squirrels. It's all about being a man, yo. But still, if you're a man, don't you want your nuts down, not up, assuming that if they're up, your feeling kinda cold? And what about the whole new masculine cremaster thing, if your nuts are up, aren't you less macho and not more? Or are you more macho for being less? And aren't ovaries the nuts feminine? And aren't they always up and totally badass?

Something tells me I'm missing the point. Guess I'll have to see the movie or shut up.
