Longcat

Origin

Longcat is a meme built from a photo of a white cat being held under its front legs so that its body appears unusually elongated. It spread on 4chan and other image boards around 2004 to 2005, typically captioned ‘Longcat is looooong.’ The simple visual joke invited exaggeration, and users Photoshopped the cat to absurd, screen-spanning lengths. It became a foundational image-board cat meme.

Meaning & usage

Longcat is used as a playful absurdist joke about length, often stretched across a page or edited into impossible scenarios. A black counterpart dubbed ‘Tacgnol’ (Longcat spelled backward) was invented as its nemesis in mock epic ‘battles.’ The meme exemplifies the collaborative, exploitable humor of early 4chan. Its appeal is the pure silliness of insisting a cat is impossibly long.

Notable examples

Popular edits show Longcat stretching between planets or across entire web pages, and the Longcat-versus-Tacgnol ‘cosmic battle’ became a running gag. It is frequently listed among the classic image-board cat memes.
