acoustic

A coded replacement for 'autistic' used on TikTok and X to call someone clueless, awkward or behaving oddly — without tripping platform moderation. Belongs to the algospeak family alongside 'unalive' (kill/dead) and 'le dollar bean' (lesbian): sounds close enough for everyone to clock the meaning, different enough that automated filters miss it. Frequently posed as the comment-section question 'is he acoustic?' under videos of someone fumbling something. Widely criticised as an ableist slur dressed up as a joke.
