Yummy is a 2020 R&B song by Canadian artist Justin Bieber. Through a mixture of overhyped marketing, a memorable reaction from music critic Anthony Fantano, and a general distaste of the song, ACS showed interest in using the song (more specifically, the controversy surrounding its astroturfing) as a meme on January 18th, 2020, though held back until it was off the Billboard Hot 100. More than a week later on January 30th, they provided copypasta-like tweets urging readers to stream Yummy, taking a desperate tone as shown by the actual marketing.
The meme saw a resurgence on April 23rd when a friend tweeted about Yummy, and ACS redesigned their twitter in the same vein as the Sand and Undertale Fanfiction redesigns before it. While it started like any other takeover, the tone became despotic, with tweets describing the merciless new regime led by "Supreme Leader Bieber". During a "nightly gathering", the manager of the tweets was assassinated by Skiss, revealing himself to be a highly decorated secret agent, having faked his death months prior (the manager's final tweet was a reference to a clip of Justin Bieber getting hit with a water bottle onstage). ACS restored the twitter the following morning.
