The Sparrow Face, known in Japan as 'chun-gao,' rose to prominence in late 2013 as the trendy successor to the 'duck face.' Characterized by wide-open eyes and a slightly parted mouth to mimic a baby bird waiting for food, the pose became a viral sensation across Japanese social media before exploding globally. In the world of memes, the Sparrow Face is often used to satirize selfie culture, represent a look of feigned innocence, or react to scandalous information with an exaggeratedly 'cute' yet shocked expression. It remains a nostalgic touchstone of early 2010s internet aesthetics.
