I have noticed that when young humans talk to other young humans, they often call them “gaur”, even though this is usually not their real name.
Like when you say:
It means "dude".
There are many different types of gaurar. The people who help me with this internet do not really know all of them, even though they are very clever.
A “klikkaður gaur” is someone who has just done something very interesting with his skate-board or his snow-board.
A “góður gaur” is someone who will buy you a bjór or drive you to töff places in an auto-mobíle.
And “Gaurinn” means “The Dude”.
If you are a young person who likes to say clever things to your friends, this word can be very useful to you.
