The 'Oh Baby, a Triple!' meme stems from a viral 2010 Call of Duty gameplay clip featuring a young player named 'Mom's Spaghetti.' After achieving three kills with a single sniper shot, the player reacts with high-pitched, breathless excitement, yelling the iconic line. The clip became a foundational element of the MLG (Major League Gaming) parody subculture on YouTube, often paired with air horns, strobe effects, and quick-scope montages. Today, the phrase is used across social media to celebrate any instance where three things occur simultaneously, often with a nostalgic nod to early YouTube gaming culture.
