I know somebody who knew him, the “viking”. The German term “Arschloch” or maybe “bully” describes that person best, as I have heard it, but this is after all hear-say and take it -like me- with a grain of salt. But the description, time and place was absolutely spot-on, so make of it what you want. Btw im telling this to the internet for years, nobody believes me & I don’t care. I can just tell what’s told me.
