The 'Ship Your Enemies Glitter' phenomenon began as a viral marketing stunt in early 2015 when Australian entrepreneur Mathew Carpenter launched a service to mail anonymous envelopes of glitter to people you dislike. The website's pitch—sending the 'herpes of the craft world' to ruin someone's day—was so absurd it became an overnight sensation, garnering millions of hits and spawning a wave of copycats. In the meme world, it has evolved into a symbol for petty revenge and the ultimate minor inconvenience. People use the template to joke about office rivalries, annoying friends, or the inevitable mess that comes from a seemingly harmless prank.
