GG has been the traditional good game sign off in competitive gaming for decades, and in Dota 2 it is the call that formally ends a match when a team concedes. Professional broadcasts made caster calls part of the spectacle, with their reactions clipped and shared on forums, streams and soundboards during the growth of Dota 2 esports in the 2010s. Short caster exclamations spread because they work outside the game too, as a shorthand for defeat, respect or a fight that is already decided.
