Reaction Images
Published September 24, 2026
Reaction images are pictures or animated GIFs used to show a specific emotion in response to something posted online, first circulating on Futaba Channel and 4chan before jumping to Tumblr, Reddit, and beyond. Facepalm entries on Urban Dictionary in 2004, 4chan's 'my face when' game, and databases like MyFaceWhen.com built the format into a shared visual vocabulary that eventually earned its own museum exhibit in 2014.
Overview
Reaction images cover a wide spectrum: cropped screencaps from film and TV, drawn faces like rage comic panels, and looping GIFs that punctuate a comment thread the way an emoticon punctuates a chat message4. Users pair a picture with a scenario, often written as 'my face when' followed by a prompt, so the expression carries the joke rather than the words1. Common categories include shock, disgust, smug approval, and the classic facepalm.
Two long-running subgenres show the range. Rage comic panels use crude black-and-white drawings and were built by regular posters through web apps that supplied stock faces4. Photo-based reactions like the Massimo d'Alema face, a shot of the Italian politician looking stunned, showed how a single frame of a public figure could carry a repeating gag; that image was already circulating in archived 4chan threads2. Computer reaction faces are a smaller subset drawn as comics showing what the poster feels while staring at their screen4.
Origin & Background
How It Spread
How to Use This Meme
The typical pattern pairs a short scenario, often prefixed with 'mfw' or 'my face when,' with an image or GIF whose expression matches the feeling. People commonly build personal folders of go-to faces sorted by mood (shocked, smug, disgusted, crying) and pull one out mid-thread instead of writing a reply.
