The Dat Boi meme first spread in 2016, built around a photo of a green frog riding a small unicycle, captioned with the phrase 'here come dat boi' and the greeting 'oh shit waddup'. Shared widely on Tumblr, Reddit and Facebook, it became one of the defining reaction images of that year, used to announce an arrival with playful absurdity. As short-form video grew, the spoken version travelled to TikTok and soundboards, where creators kept it alive for entrances and reveals. Its simple joke and instantly recognisable voice have kept it in regular use long after its peak.
