Epic Save / What a Save:

Epic Save is an in-game save award in Rocket League for stopping a shot that was heading toward the goal, while “What a Save!” is the quick-chat message players often use after a save or, sometimes, sarcastically after conceding a goal.

The award appears on the scoreboard as a recognition of a particularly important save. In play, “What a Save!” is a common phrase in Rocket League culture and can be used sincerely to praise a defensive play or to taunt an opponent.
