If said in simple words, a Managing Director and chairman will remain so, irrespective of the tag he/she chose for self. In most cases, he/she will act and behave like an MD or Chairperson as well.
At the peak of his glory, Subrata Roy used to call himself “Managing worker and chairman” of Sahara Group. He also used to post-fix ‘Sahara’ to his name. I don’t know about others, but I’ve a strong dislike for such exhibitionism. I see these not more than a constant attempt to attract attention to oneself. I also see it as a diversionary tactic. If said in simple words, a Managing Director and chairman, will remain so, irrespective of the tag he/she chose for self. In most cases, he/she will act and behave like an MD or Chairperson as well. The same logic applies to ‘Pradhan Sevak’ or Pradhan Mantri. Even if a Pradhan Mantri (Prime Minister) starts calling self, a Pradhan Sevak, that doesn’t mean much.
That said, I will not use the word dislike here, but I don’t particularly understand people who have a habit of coining Acronyms (such as NASA, VIP etc.) and using Acronyms, every now and then.
The primary reason for this is that, I think the penchant for coining acronyms is a plain waste of valuable time and focus. The moment a person coins or uses an Acronym (VIP or Very Important Person, BiMaRU or Bihar, Madhya Pradesh, Rajasthan, Uttar Pradesh etc.) he/she makes the problem shallow or trivial. If said in simple words, the moment a person coins or uses an acronym, he/she tries to make an indirect attempt to refer to an issue which needs serious and more direct attention. Thus Acronyms used every now then, don’t mean much.
More recently, the Indian Prime Minister Mr. Narednra Modi coined another acronym, EPI, which according to him means Every Person Important. EPI is one more addition to his rich collection of Acronyms!
