When I was stuck in holloway road station with a bunch of Partizan belgrade fans I feared the worse.
Partizan fans are so mental they have two factions that are segregated at matches. If you want to see a tasty local derby look up the Eternal Derby between Partizan and Red Star. Makes the NLD look like a Holland Park ladies lunch.
Oddly, just the other day I was looking at my old flying suit from when I displayed aeroplanes for mental Serbs. It's got badges on. Serbian badges. With... symbols.
Basically, I used to walk around airshows wearing Nazi regalia
