Damage incurred while there is a difference in the lives of two characters in a stock round of super smash brothers.
Link is playing Kirby on final destination. Link has 3 lives, and he kills Kirby leaving Kirby with 2 lives. Link racks up 43 damage before he is killed. Now they both have two lives, but Link has 43 bonus damage on Kirby.
