Will PM Modi's 'Didi O Didi' chant backfire for BJP in Bengal?

Ahead of the third phase of polling in Bengal, a political slugfest has erupted between TMC and BJP over PM Modi's Didi-o-Didi remarks during rallies.

Three Trinamool Congress women leaders, including Bengal minister Sashi Panja, accused the prime minister of showing disrespect to Chief Minister Mamata Banerjee by way of his "mocking tone" of addressing her at election rallies.

Panja said that PM Modi, through his sarcastic "Didi-o-Didi" (listen elder sister) exclamations at public meetings, "insults not only Banerjee, but the women of Bengal in particular."

The TMC has also filed a complaint with the Election Commission. While BJP said the words were uttered endearingly. So, the big question is will PM Modi's didi-o-didi remarks backfire for the BJP?
