Hello? Hello? Anybody home?...

Biff was born on March 26, 1937in Hill Valley, California. He is the great-grandson of Buford "Mad Dog" Tannen and the grandfather of Griff Tannen. He is not very bright and only got through high school by bullying George McFly to do his homework for him. Biff is feared by most of his schoolmates. He is less brave when he is without his gang (Match, Skinhead, and 3-D). He also has a crush on Lorraine Baines and constantly refers to her as "my girl." Lorraine does not return the sentiments.

By 1985, Biff's marital status is unknown – no mention of a wife or children was ever made in the trilogy, although Biff has a grandson Griff by 2015, suggesting that Biff had at least one child by 1985. The animated series reveals that Biff has a son, Biff, Jr., (who, according to an early script for Back to the Future Part II, owns the Cafe 80's), although this is not taken as canon by many fans. A draft script reveals that his middle initial is "H" for "Howard", although his middle name was never mentioned in the trilogy. Also, a BTTF comic showed a "Mugsy Tannen" living in 1920's Prohibition-era Chicago as a gang boss, probably Mad Dog's son.

Biff is noted for mangling similes: for example, he says "make like a tree and get out of here" instead of "make like a tree and leave" on more than one occasion. He also once says "That's about as funny as a screen door on a battleship" instead of submarine. He is also known for calling people "butthead". When someone says something foolish, he knocks on their head with his fist (or a fist-shaped cane in his old age) saying "Hello? Hello? Anybody home?" His attitude is to do something rather than think things over, and he has no problems with using his fists to get what he wants. Biff will try and get out of paying for things if he has to and is looking for a nice easy life where everyone else will do things for him. He also likes cars and ends up with a career waxing and cleaning them with his auto-detailing business. Biff is still a bully, but can be nice and/or charming when he needs to be, usually to get out of trouble.
