Dhinchak is an attitude. It's what makes the kudi from Janakpuri who aspires to be in South Delhi actually get to Sainik Farms. Dhinchak is in the tinkle of the glass bangles and the sparkle of the bindi that she effortlessly teams with bootcut jeans to get noticed. Dhinchak is that quintessential free-spiritedness that makes a Janakpuri ki ladki smile and bullshit her way out of a sticky situation.
Dhinchak is never a size zero because she wont ever give up on that spot of butter on her aloo ka paratha or fail to gobble the last garma-garam gulab jamun. Dhinchak will always be slightly conscious of her surroundings and her short skirt when she goes to celebrate her anniversary (not birthday) at The Oberoi (in South Delhi,of course), a once-in-a-year affair that will be duly documented on Facebook, except that she will call it Oberois.
