The Brainrot emote in Jujutsu Shenanigans appears to have been added in the 1.76 update around May 20–22, 2026 based on update videos and emote listings from that period.

Quick scoop

  • A JJS 1.76 update video from May 20, 2026 lists Brainrot among the new emotes.
  • Another upload about “every new emote in jjs” is dated May 21, 2026 and includes the same update timeframe.
  • That makes late May 2026 the best-supported release window for the emote.

Note

  • I’m treating “came out” as the first public appearance of the emote in the update cycle, since that’s what the available sources show.
  • If you meant a different “brainrot” emote or a specific JJS patch, the exact date could shift a bit.
