A secret and cryptic language used by black haired and pierce wearing humanoid beings known as "emos".
Person1: rawr :3
Person2: what?
*person 1 proceeds to walk a way from person 2 with a disgusted look on his face.*
a rawr is when you feel like rawring out loud but instead you feel the urge to type it.
When a girl says RAWR they normally have long finger nails. They are normally smaller than average size, and are trying to intimidate a friend into letting them type. Ouch.
Girl: OMG LET ME TYPE! Rawr
Guy: AAAH DEAR LORD HELP ME
It means "I love you" in dinosaur.
Person one: Rawr~
Person two: aww I love you too
