The Side Part vs. Middle Part debate emerged as a defining cultural clash between Millennials and Gen Z on platforms like TikTok around early 2021. Gen Z creators began declaring the side part—a staple of 2000s and 2010s fashion—as 'cheugy' or outdated, insisting that only a middle part is flattering. Millennials fired back, defending their hair choices and sparking a viral war of words through videos and image macros. The meme represents broader generational differences in fashion, aesthetics, and the cyclical nature of trends, often used to poke fun at the intense loyalty people feel toward their preferred hair styling.
