Ara ara is a long-standing Japanese expression meaning roughly oh my or my my, heard for years in anime and manga from calm, mature female characters. Online, the phrase was clipped into a standalone reaction sound and spread through anime edits, compilations and soundboards alongside other short voice memes like Tuturu and Yamate Kudesai. Its appeal comes from how much character it packs into two repeated words, signalling teasing affection without needing context, which is why creators still reuse it across fan edits and social clips today.
