The phrase comes from everyday Turkish, where a limoncu is a lemon seller who would call out to announce his arrival in a neighbourhood or market. Online, the exaggerated recording circulates as a short soundboard clip among Turkish speaking users and meme editors. Its humour relies on treating a routine street call like a heroic entrance, so it gets reused for arrivals, pop ups and product reveals. The drawn out ending makes it easy to recognise even out of context, helping it survive as a reusable reaction sound.
