Moms know just about everything, right? Like Santa, they know when you've been naughty, they know when you've been nice. It turns out, though, there are some things they don't know.

Those things are porn terms. In this somewhat NSFW video, a group of moms are put to the test, trying their best to guess some well-known phrases relating to sex.

Moms may know how to tape up that boo-boo, bake a special cake, or give the perfect hug after you've had a bad dream, but, like you and ninth-grade algebra, they simply do not know porn. And that's probably a good thing, right? Do you really want to be able to have a conversation with your mother about the "glory hole?" That just seems so wrong.
