They are in brotherhood with the organized fan group of FK Zemun , the Taurunum Boys . They have this relationship since 1998 . It all began when a prominent Taurunum Boy member has lived and has a family in Kragujevac and the Taurunum Boys visited a barrage match back when Radnički Kragujevac fought to enter the major leagues . Ever since then the brotherhood has been growing and growing , and today it has been passed to the younger generations . The Djavoli have also a long friendship with fans of Sloga Kraljevo , the Kasapi ( " The Butchers " ) . This friendship can be seen during football and basketball matches , where they chant together in the stands . It also started recently good relations with the organized supporters of Radnički Niš , the Meraklije . Their relations began mainly through the mutual support of the growing local patriotism in the Serbian fan scene . There is a connection between the clubs as they share the year which they were founded , 1923 . Also , both groups were founded in the same year , in 1989 . The name Radnički means " Labour ´s " in Serbian and its roots come from the relations which the clubs had with Labour movements during the first half of the 20th century . Their often mentioned slogan is : ' '' " Radnička deca , radnička braća " ' '' , which translates to " Workers children , workers brothers " . Another connection is their anti-fascist attitude through similar tragedies which happened in both cities during the World War II . In the city of Kragujevac the Kragujevac massacre and in Niš the Bubanj massacre , both committed by Nazi German soldiers , which had in both cities a strong influence on subsequent generations . All reasons , why the first top tier match between these clubs ended during the 2012 – 13 season especially in a respectful and peaceful atmosphere for each other , although they not played against each other for a long time
