My dad is a fan of Bollywood actor Salman Khan. He loves watching his movies.
One moment, he took his sunglasses, started to hang on the back side of my shirt and said, "Hud.. hud.. Dabanng, Dabanng". But I overheard the word and repeated "Daa-bam Daa-bam".
My mom recollects today that - every moment I see sunglasses, I utter Daa-bam, Daa-Bam.
Now it is a word for me to indicate sunglasses.
