Cantiknya comes from Indonesian, where the word is used to admire beauty, and it has travelled online as a short reaction clip shared through meme pages and short-form video. Its appeal is partly linguistic and partly visual: even viewers who do not understand the word can read the admiring tone from the context, while Indonesian and Malay speakers recognise it immediately. That mix of familiarity and novelty has kept it useful for creators who want a quick, positive reaction without a long voice line or a generic effect, especially in fashion, beauty, travel, and pet content.
