The exact origin of the Ridma Thathsara clip is unclear, as it surfaced through user uploads in TikTok trend circles rather than an identifiable show, film or song. Short name-based tags like this often start as an inside joke, a creator saying a friend's name on camera, then get clipped and reused because the delivery is catchy. With just over a second of audio and only a handful of early plays, it sits in that early meme stage where small editors adopt it for personalized jokes, shout-outs and reaction cuts before any wider trend forms.
