YTMND
ytmnd, an acronym for "You're the Man Now, Dog", is an online community centered on the creation of hosted memetic 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 a humor website, owing its tone and culture to the original YTMND and its early imitators. Other YTMNDs, however, are artistic or political.
