Further confirming that your BBQ chip and marshmallow fluff sandwich is far from okay, researchers at the University of Alabama have released a study which reveals secretive "food concocting" is a new identifier of binge eaters. Since word also dropped that Taco Bell is expanding their Dorito tacos with a new Cool Ranch variety, we figured now was as good a time as any to recap some of the most disgusting food mash-ups on the market. (After all, Thrillist is kind of an expert on this subject.) Gentlemen, brace your gag reflexes.

Cone Crust Pizza (Pizza Hut)
If you thought Pizza Hut's hot dog-stuffed pizza was bad, steel your stomach, 'cause this pie might make you spew. The Cone Crust Pizza swaps out a normal crust for Parmesan-crusted dough cones stuffed with either -- no, this is not a joke -- honey mustard chicken or Philadelphia cream cheese. It hasn't managed to creep its way over from the Middle East yet, so if you actually want some of this pizza nightmare, you're going to have to book a plane ticket.

Bacon Sundae (Burger King)
Yes, bacon is possibly probably definitely the most delicious food on the face of this earth, but everything has a line. Burger King made a mad dash past that line with its bacon sundae, a stunning blend of vanilla ice cream, fudge, caramel, bacon bits, and one whole piece of bacon. It also boasts 61 grams of sugar, so on top of the turmoil it will put your digestive system through, it'll also probably clinch you a root canal appointment.

Wasabi Cheese Donut (Dunkin' Donuts)
Only those residing in Singapore can experience the, um, joy that comes with ingesting a wasabi cheese donut (fourth, second row). Apparently things just get weird at Dunkin' Donuts once you go abroad -- other international flavors include kimchi and dry pork and seaweed.

Mac and Cheese Big Daddy Patty Melt (Denny's)
This monster of a sandwich consists of "a hand-pressed beef patty topped with new creamy Mac 'n Cheese, melted cheddar cheese, and zesty Frisco sauce on grilled potato bread." It is also 1,690 calories. Happy dry heaving.

Double Down (KFC)
Many have heard of the Double Down, but few have had the guts to order this terrifying breadless atrocity. With two white chicken filets, bacon, Monterey Jack and pepper jack cheeses, and Colonel's Sauce, the Double Down reached the pinnacle of fatty fast food sandwiches and never looked back.
