u actually believe tat's a burger call mc gangbang??!!! *press
laugh button*

The McGangBang ranks up there in the holy pantheon of WTF. It's
a sandwich made from a double cheeseburger and a McChicken sandwich
— where you put an entire McChicken sandwich inside a
double cheeseburger. It's a creative manipulation of
existing menu items, and an exercise in frugality: taking two items
off of the Dollar Menu and creating an entirely new sandwich for a
total of $2.16. Truly, it's a sandwich that's more than the sum of
its parts.
The naming, of course, is somewhat obscene — "gangbang" is
defined as "sexual intercourse with multiple partners in turn or at
the same time." It's illicit in more ways than one — chicken and
beef most definitely make for an unnatural pairing.
In addition, it's sort of a subversive act for people to order
it by name, as well as a thrill to confound the McDonald's employee
with an order for a McGangBang — so much so that people are
documenting their experiences at drive-thrus and counters on
YouTube
