1.
A word used to describe Mr. Narendra Modi for his penchant for braggadocio regarding his achievements. Derived from the Hindi word (Phenku) which literally means: someone who throws. Usually used for someone who is bullshitting.

Made popular as a twitter hashtag and is now used to refer to him and his pronouncements (sometimes even on Television). His supporters known as Sanghis, inspired by him have a similar penchant for even greater levels of braggadocio for e.g. Petrol will be available for Rs. 10 a litre once Feku comes to power.
Feku said that the school drop-out rate is less than 2% (when actually it is closer to 7%)
Feku says that all the Okra eaten in Europe comes from his state.
