A Geddicorn is a mythical creature similar to a unicorn. It is a good-looking female that attends a RUSH concert without having to be coaxed to do so by a dude.
She is turned on by Geddy Lee and not afraid to show it.
I went to the RUSH show last night and saw the hottest Geddicorn ever. She was in the 4th row on Geddy's side and wasn't even with a dude!
get - it? Said fast usually after you tell a joke and to wait for a response to the person you told it to, particularly if it's a tricky or subtle or to avoid causing offence etc.
We are a fairly large group of friends from Bergen, Norway and this expression was born when a friend of our started with some strange behaviour. When we were hanging out he suddenly just left and did not return for several hours. The strange thing about it was that he acted like nothing had happen. This happened from time to time for a few years, and to this day we still have no clue what he did or where he was. From that day the expression has grown from our little click to become a more or less common word in our city amoung the youth.
Means: get the f**k out of here.
Used to tell your opponent to simply go dump themselves into a trash can or something because they are saying absolute nonsense.
