LOL began as internet shorthand for laughing out loud in early online chat and texting, where it became a quick way to show amusement without typing a full reaction. As social media and short video grew, the phrase moved beyond text and into meme culture, where a spoken laugh became a handy reaction clip for jokes, fails and lighthearted posts. Like a baby laughing meme, it works because the sound is instantly understood across languages and platforms, which is why creators still reach for this kind of meme laughter today.
