Cutie patootie is a rhyming slang phrase that has long been used as a playful nickname for someone attractive or adorable, and the short audio version became popular as a reaction sound on social media.

Creators reuse it as shorthand for affectionate teasing, letting a single phrase do the work of a compliment, a caption, and a punchline at the same time in short form video.
