Nanu mama used say "Tagra Raho" while saying goodbye, which is the regimental salutation of the Assam Regiment ("stay strong/fit") in the Indian Army.
This is the joke he sent last year.
A Assam Regt officer told me this story. Some ASSAM bn personnel were attached for guard duties in the GOC's House. One of the men had to go into the House and whenever he would meet the GOC's Wife Greet her Loudly . The GOC's wife was on the obese side.This daily greeting by the soldier was not liked by her. She conveyed her displeasure to her husband stating that he was poking fun, of her obesity. The GOC promptly summoned the CO of the Battalion.The CO told the GOC that he knew the soldier, who was sincere and an outstanding soldier and he would not make fun of any lady and more so the GOC's wife.The CO asked , as to what exactly did the soldier say. The GOC rang up his wife, who said"TAGDA RAHO MEM SAHAB" Both the GOC and the CO burst out laughing, for it was the ASSAM Regimental Greeting. The GOC requested that the soldier be asked to greet his wife with 'Namaste Memsaheb'......☺️☺️
