No, that was for a purpose.
Hathura being BD coach for long, he knew Nazmul's celebration. When he became SRL coach and immediately they played against us, he enticed his players to mocked BD players with that Nagin dance, which was absolutely disgusting from him, after being BD coach for 3 years. Then the SRL crowd again started it in the first game of Nidahas trophy. In fact, in latest game in Asia Cup, it was a SRL lady in crowd was seen doing same and BD players were quite sober after that win.
I am absolutely OK to return back the compliment if someone plays dirty. In fact, it was quite distasteful for AFGs to mock BD players in the T20 series, which was understandably praised in PP.
Regarding arrogance, you are part of that, hence couldn't notice it - do a soul searching, ask 30 neutral people and get your facts checked.
