若当我是游戏定开挂虐死你
[ruò dāng wŏ shì yóu xì dìng kāi guà nüè sĭ nĭ]
This internet name shows a confrontational attitude. If you see me as a game ('If you think this relationship/life is just a play'), I'll show my dominance (use cheats) and completely dominate over you, leaving you helpless in this context. Implies an intention not to be toyed with or undervalued.
