The phrase 'Ay Cabrón' is a common Spanish exclamation used to signify surprise, disbelief, or intense realization, making the template perfect for 'that moment when' scenarios. It gained significant traction on platforms like Facebook and TikTok within the Hispanic community before crossing over into global meme culture. The meme often leans into 'cursed' or bootleg aesthetics, emphasizing the chaotic energy of Bart's expression to highlight relatable, high-stakes, or absurd situations.
