Of course not. That is long story and I do not want to write about that here and why is that nickname, because some minority can feel ofended. Fans of other rival club (Partizan) give that nickname. Real nickname of Red Star fans is "Delije", which means worriors, hero, brave... By the way, until recently, their stadium was called Marakana, same as in Brazil. Because, I think, when stadion was built, it was maybe biggest in Europe. In 1975, I was kid and watch game against Ferencvarosh. There was 110.000 fans. I am not sure is that still the most attendance in Europe.What? Red Star's fans call themselves like that (proudly).
