From PUBG's English victory line 'Winner Winner Chicken Dinner', translated as
大吉大利,
今晚吃鸡 (Dàjí dàlì, jīn wǎn chījī, 'great fortune, chicken for dinner').
吃鸡 became shorthand for both the game itself and battle-royale games in general — including
和平精英 (Hépíng Jīngyīng, the mainland-China version of PUBG Mobile).
