The 'Who Gon Check Me Boo' meme originated from a heated exchange during the second season of The Real Housewives of Atlanta in 2009. Reality star Shereé Whitfield uttered the now-legendary phrase during a confrontation with an aggressive party planner who threatened to 'check' her. Since then, the clip has become a pillar of internet culture, symbolizing peak confidence, untouchable status, and a refusal to be intimidated. It is widely used in social media reactions to dismiss critics or to playfully assert that one is doing exactly what they want regardless of outside opinions.
