The information I am getting that, probably this celebration is reserved for SRL only. In future, either it’ll end or come back only against SRL - reason mentioned in my earlier post. The inside information is that, Hathura joining SRL, immediately after leaving BD job, knew BD players too closely - he instigated Lankan players to mock BD players, some of them picked the celebration from Nazmul AND it worked indeed.
Personally, I don’t mind any such gesture or body language which is universally accepted as offensive, vulgar or symbolic. I have seen players mimicking many such facial impressions or body movements which was/is perfectly acceptable - for me, than using middle finger. Old West Indian team was famous for copying in dances & they were dam good at that - and I enjoyed them equally as their cricket; never felt anything wrong or disgusting when a 6’9” man is doing Waltz in front of whole stadium with his 6’4” team mate.
I am sure, this Nagin dance would have been accepted as well, unless it was Bangladesh. For example, Lankans started this at Dhaka & going by the post in those game threads, it suggests many here had seen those games indeed - BD lost, so no reason to miss the fun. But, either they didn’t notice it as it was from Lanka or didn’t feel they need to put a judgement there, again as it was Lanka.
That tells me that, it’s a problem with Bangladesh, not the Nagin celebration; which is unfortunate - it doesn’t reflect a good taste to be honest.
