Picture the grossest apartment a male date or friend ever brought you back to. Why are they like this? That’s the question Brooklyn-based comedian Rachel Coster explores in her new, instantly viral video series, called “Boy Room.” In it, she tours and investigates the apartments of 20-something men — which are just as filthy, perplexing, and unhinged as you’d expect. Yes, there are the random dirty dishes, curtainless windows, and basic metal bed frames. But there’s also a guy who appears to keep his clothes in moving boxes, despite the fact that his drawers are basically empty. Another decorates with random bikes he’s working on…and not in a cool, creative way. And a third framed and hung his old rat tail on his wall (certainly not in a cool, creative way).

It’s the type of thing that we’ve all probably seen some version of (by the way, you can nominate “Boy Room” candidates here), yet it’s still oddly mesmerizing. That probably explains why the series — perfectly described as “a quasi–nature documentary” — already has millions of views and thousands of comments. While many commenters recount their own horrifying boy room encounters, some point out that it’s not just men who are messy. “Could Girl Car be a spinoff?” one Instagram user asked, which, fair. Others chime in with decorating advice — something Coster also does at the end of each episode. TBD if the boys behind the rooms are taking it.
