Meant to be said with a group of people in a raindrop (One person says it, than more and more to the point its almost rabble) fashion while greeting somebody. It is the only word said throughout the whole conversation. This word is designed to leave the person your greeting scratching there head and saying What the Fuck!? It has no real meaning other than the intent to completely shock and dazzle the person being greeted. It is not from the German Language.
(Group of people walk up to a doorbell and ring it, Rhuwell comes to the door)

Person 2,1: Schtimen
Person 3,1: Schtimen
Person 4,1,2,3: Schtimen

Person 5: Schtimen
