The emoticon is made up of the letters X and D, where X is the eyes all scrunched up, and D represents a really big mouth that is laughing. XD has a similar meaning to LOL, or âlaughing out loud,â in Internet slang. To see the face created by the letters XD, one can turn her head anticlockwise. Using a colon next to a capital D or typing X-D during an Internet chat also means the person is laughing crazily.Learn more about Mobile.
