A hero sandwich was a large sandwich on a long thick bread bun, which contained a variety of different fillings.
Having memorized whole sections of How to Win Friends and Influence People by Dale Carnegie in 1954, George McFly had a hero sandwich rubbed into his face by Biff Tannen on their first encounter at Hill Valley High School, when Mr. Carnegie's claim that a man could not remain hostile if one showed one was sincerely interested in him proved somewhat ineffective.
