XD 

A symbol with X being the eyes and D being the mouth, to make a seeming of the person having squinched eyes and a mouth wide open laughing. This is usually used to replace rofl, as the X for eyes indicates that they are laughing so hard they may have fallen off their chair. Usually used in mmorpgs and chat lines.

Example 1:
Person 1: Hah i hacked some n00b's account then went and spammed lots of people and got it reported!!1!

Person 2: Omg XD haha he must be so pissed!
