The 'Small Waist Pretty Face With A Big Bank' challenge is a viral social media trend primarily popular on TikTok, centered around lyrics from the song 'Mean' by Bankrol Hayden. The trend involves creators syncing their movements or showcasing transitions to the catchy rhythm of the line, often highlighting personal confidence, style, or financial success. While it started as a genuine flex or dance challenge, the internet quickly adapted it into a meme format used for ironic reveals, glow-ups, or humorous comparisons where the 'big bank' or 'small waist' might be something unexpected or absurd. It remains a staple of short-form video culture, symbolizing the intersection of hip-hop influence and self-expression on social platforms.
