The phrase liang liang de literally suggests something bright and shiny in Mandarin, which helps explain why the clip is usually attached to sparkling or eye-catching moments online. As a soundboard meme it has circulated mainly as a tiny reaction sound rather than as part of a longer song or dialogue, making it easy to drop into short-form videos, edits and streams. Its appeal comes from its brevity and cheerful tone, so creators keep reusing it whenever they want a quick, cute emphasis without interrupting the scene.
