Geroya be Haran meant "game of annihilation". Unlike other duels fought by Mandalorians of the era over matters of personal honor, the Geroya be Haran held a unique penalty for the loser: every achievement, and even their very memory, was expunged from Mandalorian history as though they had never existed.
