Etymology. “Eighty-Twenty” spells out “80/20”; both refer to the same imbalanced position. The spelled-out form predominates in casual spoken vocabulary.
Mechanics. The configuration’s mechanical asymmetry produces a clear leverage advantage for one player — the lower-leverage player’s primary task is escape or rebalancing.
