GG has been gaming shorthand for good game for decades, typed or spoken at the end of competitive matches as a sign of sportsmanship. Mongraal, the online name of British Fortnite player Kyle Jackson, became one of the game's most recognised competitive and streaming figures, which made his name a frequent reference in clips and edits. Short voice lines naming him spread through gaming soundboards and short videos, where creators reuse them as an instant, recognisable sign off rather than recording their own version every time.
