D.Va, real name Hana Song, is a playable hero in Blizzard's team shooter Overwatch, first released in 2016. Her ultimate ability, Self-Destruct, ejects her from her mech before it explodes, and she announces it with the line Nerf This. The voice line quickly became one of the game's most quoted moments, shared in gameplay clips, streams, and memes long after its release. It remains popular because it is short, confident, and instantly signals a big, destructive play, even to viewers who do not play Overwatch.
