Wikipedia:
"YTMND, an initialism for "You're the Man Now, Dog", is an online community centered on the creation of hosted memetic (or memes) web pages (known within the community as fads, YTMNDs or sites) featuring a juxtaposition of an image (still or short animation) centered or tiled along with optional large zooming text and a looping sound file. Images and sound files used in YTMNDs are usually either created or edited by users. YTMND is generally considered to be a humor website, owing its tone and culture to the original YTMND and its early imitators."It's still going apparently:
https://ytmnd.com/I was just remembering all of the memes, and then the memes based on older memes. Those were the days. Anybody remember this website from the mid-2000s?
The original meme started from
THIS, and it exploded into hundreds of memes from there.
