Vibrating GIFs are animated images edited to shake violently in place, used as reaction images on forums and image boards starting in 2011. A bug-eyed dolphin posted to an obscure Blogspot site kicked off a template that spread to Tumblr tutorials, 4chan threads and brony boards.
Origin
The earliest documented vibrating GIF went up on the Worst Fucking Blog Ever on March 31, 2011, a tightly cropped photo of a bug-eyed dolphin shaking in place under the caption "I don't know why this is so funny"[3]. The post itself was offhand and the blog small, but the file format was the point, a looped jitter that read as an emotion rather than an action.
No single creator claimed authorship of the vibrating GIF technique itself; the Blogspot post is the earliest surviving example rather than a confirmed invention of the format[1]. Within weeks of that dolphin, tutorials appeared showing readers how to replicate the effect in free and paid editors[2].

Overview
Vibrating GIFs are static images, usually a cropped face or character portrait, animated so the subject jitters back and forth at high frequency instead of moving through any real action[1]. The jitter does the comedic work on its own, reading as pent-up rage, excitement or sheer intensity, which is why posters drop them into threads as reaction images rather than as standalone jokes[1].
The format caught on partly because it was easy to produce once a tutorial existed. Early guides walked users through duplicating a photo layer, shifting the copies a few pixels left and right, dropping their opacity to around 30 percent and merging them into a frame loop, first in GIMP and later in Photoshop CS5[2]. That low barrier to entry meant any portrait could be turned into a reaction GIF of a shaking cereal mascot, anime character or cartoon pony within minutes.
