The “Big Bank Challenge 🍑” is a TikTok/short-video trend centered on showing off body shape, particularly the waist, face, and buttocks. The 🍑 emoji is commonly used as a euphemism for the butt.
The trend is associated with “Mean” by $NOT featuring Flo Milli, especially the lyric about having a “small waist, pretty face with a big bank.” Participants typically pose or dance while the camera shifts attention from the face/waist toward the rear at the relevant part of the audio.
For the video you linked, the “challenge” isn’t a food or money challenge—the “big bank” wording is slang referring to a fuller/larger butt. Similar videos using #bigbankchallenge are still circulating on short-video platforms.
