The ROFLcopter comes from early 2000s forum and gaming slang, where ROFL meant rolling on the floor laughing and users drew a helicopter out of text characters. Adding SOI SOI SOI gave the ASCII copter a voice, as if the blades were chanting while it flew. The joke spread through forums, chat rooms and early meme videos, long before modern soundboards. It survives now as pure nostalgia, a deliberately dated way to laugh at something so unfunny or absurd that an overblown reaction becomes the punchline itself.
