The phrase snake in the grass is a long-standing English idiom for someone who seems harmless but acts deceitfully, and it fits Conor McGregor's outspoken, confrontational interview style perfectly. Short clips of the Irish mixed martial artist have circulated widely on soundboards, meme pages and short-form video, where his voice alone signals a call-out. Because the line is brief and instantly recognisable, editors keep reusing it whenever a clip needs a sharp, accusatory reaction, especially in sports edits, gaming moments and comedy sketches about betrayal or backstabbing.
