XD is simple, yet elegant. If you don’t see it instantly, stare at it for a while. Then look away. Then look back. See it? An uncontrollably laughing face. Think about it more, and you realize the X looks like that because of the resemblance to two eyes closed in hysterical glee. To be honest, it’s the face that will take over LOL.

Do you know how (or why) anyone would use this versatile expression? Well, in many online games, there are no emojis to chat with. This limits poeople to : D, : ). *-*, the list goes on. XD is the perfect way to get across the feeling of joy emoji, or the laughing emoji. Other form include xD, which is almost the same, xd, which is for sarcastic/ironic laughing, and Xd, which is for people who couldn’t care less. 

Person 1: “LOL I destroyed you in that game yesterday”

Person 2: “Yeah XD“
