The XD face began as a text emoticon in early internet chats and forums, meant to show eyes squeezed shut while laughing, similar to a cartoon character cracking up. As meme culture moved to image macros, video edits and soundboards, the expression became shorthand for finding something absurdly funny. Short XD clips like this one spread through prank and reaction videos, where creators needed a universal laugh signal that works across languages. It remains popular because the meaning is clear in a second, even in Spanish speaking prank content shared online.
