Gerber BAaby also known as Baby Covering Mouth, Niche Baby, Baby With Motion, Son Baby, Tuff Baby, AI Baby Laughing or Say You Swear Baby, refers to a video edit of a baby rotoscoped, seemingly with an AI Video tool, onto an adult man performing gestures like covering its mouth, as if covering a smile or laugh, to express shock or excitement. The original video, before the rotoscoping, was sourced from Chinese social media, coming from the short-form video influencer Xiucai ("秀才"), showing him lip dubbing the song "Sweet Love" by Chen Yujian & Wang Yuxin ("甜蜜愛情" by 陈玉建 & 王语心). Covering his mouth to hold a laugh was one of his signature moves.
In November 2025, the baby image, created by artist Dallas Rayburn, was rotoscoped onto the lip dub video, first surfacing on InstagramReels from user @daily_upl. Then, a popular edit of the video added the underground rap song "130 backpack supreme backpack" by jujuvr. The AI Baby meme then spread to Twitter / X and TikTok in the following weeks, both in video caption memes and as a reaction GIF or video.
