Remember the McGangbang? Yeah, we brought it up again -- sorry! But it got us thinking: Surely there have to be other "secret menu" items lurking out there, just waiting to be discovered. And because we live in a sick, sick world, there are. So we dug them up for you, because we're just as sick.

Check out these 5 "Secret Menu" Fast Food Sides:

Disclaimer: You may not be able to order these items by name, but if you seek mediocre thrills in life and want to give it a go, don't forget to document it on YouTube for the rest of us.

5. Burger King's Frings

Ever have trouble deciding between the King's french fries and fried onion rings, so you just order both? Well, stop being a fatty and order the frings: half fries, half rings. On second thought, why not just continue being a fatty and use those saved calories for a Mocha Frappé? You're welcome.

Rumor has it they have seasoned sweet potato curly fries now, too. Curly frings, anyone?

4. KFC's Poutine

So get this: KFC has fried potato wedges, right? And they also have gravy. Sooo it seems like a no brainer: pour the gravy all over the fries. But wait, while you're at it, ask for some of the shredded cheese they use for those questionable-sounding/I'm-actually-just-embarrassed-that-I want-to-try-one Mashed Potato Bowls.

Sure, it may not be cheese curd, but hey, you're at a fast-food chicken joint and you didn't have to step foot into Canada -- be grateful for what you have.
