It is used online as a short reaction line for downplaying romantic moments, especially in meme edits, short form videos and compilations built around awkward encounters. Because the phrase is widely understood without any context, creators reuse it over film clips, gaming moments, anime scenes and real life footage where someone tries to act unbothered. Its popularity comes from that mismatch between a small comment and a big reaction, allowing editors to reuse the same four second clip across many different situations without explaining the joke beforehand.
