A mega sandwich created by inserting a Wendy's crispy chicken deluxe sandwich in between the beef patties of a Wendy's double stack sandwich. Aptly named due to the sexual congress of Chicken, Beef, and Bacon that takes place in your mouth. Similar in theory to the McGangBang, but better due to the addition of BACON! The trifecta is completed.
Bro, I gotta drop a serious steamer, I just wolfed two Meat-nage a trois sanGwiches @ wendy's.
