It means white/pure...my friends find it funny because well....I'm not white 😆 (they don't mean it in a racist way...they are all first gen like me so we joke around) so actually my grandma named me this and it was because Amithabh Bachchan is her favorite actor so she wanted to name me after his daughter 🤣 and my Dad hates AB...he's a Rajesh Khanna fan...we have constant fan wars in my family over this...but thank god my dad didn't name me...otherwise my name would have been twinkle 🤣
