ROFLcopter is one of the oldest and most iconic internet memes, originating in the early 2000s on platforms like Warcraft III and Flash animations. It typically features an ASCII-style helicopter whose spinning blades are made of the word 'ROFL' or 'LOL.' The meme is often accompanied by the sound 'SOI SOI SOI,' a phonetic representation of Microsoft Sam's text-to-speech engine attempting to read the characters. It serves as a classic expression of extreme laughter and remains a nostalgic symbol of the early web's quirky and text-heavy humor.
