There is no widely confirmed mainstream origin attached to Nektarynki from the available facts, so it is best understood as an internet meme clip circulated under that name on soundboards and in short edits. Its appeal comes from how specific and unexpected the title sounds, which makes the audio easy to drop into surreal jokes. Like other odd one-word meme sounds, it sticks because creators can use it with almost any visual punchline without needing extra context.
