Peanut Butter Jelly Time (PBJT) is a viral flash animation that first emerged in the early 2000s, specifically around 2002 on the Offtopic forums and Newgrounds. Created by the Buckwheat Boyz, the song accompanies an 8-bit dancing banana gif, creating an infectious and slightly nonsensical loop that defined early internet humor. The meme became a cultural phenomenon, appearing in mainstream media like Family Guy and Ed, Edd n Eddy, and remains one of the most recognizable relics of the pre-YouTube era. It is typically used to represent pure, chaotic joy or simply to evoke nostalgia for the golden age of internet animations.
