What happens in the video
A guest at a quinceañera is filming the dance floor when you two-step right up to their phone. You take a big bite of a pink concha, the Mexican sweet bread with the seashell top, and chew it with full cheeks and a dead-serious stare into the lens. Then you turn around and dance back into the party, one hand in the air.
Where it comes from
It started with a real video from a quinceañera in Mexico: a man dancing up to a guest’s phone, biting a concha and staring into the camera while he chewed. TikTok set it to a sped-up cut of BbY WOW, the song by KAROL G, Judeline and rusowsky, and the bby wow guy became a trend everyone redoes with their own face.
Why people post it
The joke is the contrast: party energy, then a face that takes the concha completely seriously. It’s short, it’s silly and it works on anyone, from your dad to your best friend.
