The 80s gave us some of the greatest cinematic douchebags to ever make you cringe with disgust. Perhaps none are more memorable than Biff Tannen. Written as a broad bully type, and perfectly cast with actor Thomas F. Wilson, Tannen became a perfect foil for Marty McFly's time-jumping adventures. His bull-dog temper, inability to use common sayings correctly and propensity for date rape made him someone despicable enough to hate on, and pathetic enough to laugh at. The brilliance of the Back to the Future films is that they don't just have Biff change into a better person at the end, they go back to the root and change his bloodline to stop generations of douchebags from ever existing.
