Adjective describing a person of the upmost idiocracy. Biff is commonly used when such titles as Jackass, Retard, and Douchebag are not quite enough to describe a person. It is also commonly used to describe epic failure or defeat.

It may also be used to describe distinct personailty traits and physical features.(persistant look of confusion on ones face, excessive confidence, and a near identical cologne choice to that of Conway Twiddy)
