A clever repackaging of the parlor game Dictionary, Balderdash contains several cards with real words nobody has heard of. After one of those words has been read aloud, players try to come up with definitions that at least sound plausible, because points are later awarded for every opposing player who guessed that your definition was the correct one.

Versions of the game as a parlor game go back at least as far as 1970, although Balderdash itself was not published until 1984.
