Some old guys like hunting. Others like TV. But one fascinating subset of old guys really like getting completely covered in slime and goop. This is a fetish known as “gunge” and if you’re anything like me you have a really hard time figuring out what makes this sexy.

Of course, gunge can get really messy, so lots of people lay down protective plastic sheets to keep from staining the floors with green ooze, creating a sort of ‘gunge cave.’ How conscientious.

It’s time to dive into the world of gunge. Check out these pictures on an empty stomach, and maybe take a shower after.
