Prepare your stomach because the McDonald's "Secret Menu" may be far from myth.

In a recent Reddit AMA with a UK-based McDonald's manager, the employee revealed that customers can indeed order a secret menu item, though the items aren't as secret as you might think.

According to user OrchidHibiscus, who claims to be a shift manager at a restaurant in Glasgow, Scotland, any additional ingredient added on to an existing menu item is referred to as "grill order." For example, the employee says, a Big Mac with no pickle would be considered a "grill order."

To order off the secret menu — which the employee clarifies was not officially developed by McDonald's — just ask for additional ingredients.

"Order one and the workers might not know it by name ... but if you explain what it is, and are willing to pay for all the ingredients, it's just another 'grill order' that we can make up," writes OrchidHibiscus.

The employee referenced Secret Menu items like the Land, Sea and Air Burger ("Big Mac, Filet-O-Fish, & McChicken All in One") and the crudely named McGangbang ("A McChicken Sandwich inside of a McDouble") as potential food mashups that customers can order ingredients for.

Additionally, #HackTheMenu has a comprehensive list of items it claims can be ordered or assembled to satisfy your Secret Menu cravings.

While #HackTheMenu claims that many of their item suggestions can be ordered at all McDonald's locations, Mashable reached out to the fast food retailer for its comment on the claims:

“We do not have a secret menu at McDonald’s UK. That’s because we love the food that we serve in our restaurants and we don’t want to keep it a secret from our customers," said a McDonald's spokesperson. They did, however, acknowledge that customers can ask for changes. “Any requests for extra items or changes to our products are considered at the restaurant manager’s discretion and any additional items may be charged for.”
