Laugh Out Loud (LOL) is an acronym widely used in online conversations, text messaging, and social media to indicate amusement. It serves as a quick response to something funny or entertaining, replacing the need to type out a full sentence. While LOL was originally used to signify actual laughter, it is often used more casually in modern times to acknowledge humor, even if the person is not laughing out loud. LOL is one of the oldest and most recognized internet slang terms, remaining relevant in the digital language of Gen Z.
