The Bhai aapka knowledge toh kamaal ka hai bhai meme originates from the 2006 Indian film Phir Hera Pheri. In this Bollywood movie, Kanji Singh (the character played by Kiku Sharda) says this dialogue to Munna Bhai (the character played by Johnny Lever) when the latter states that SRB is a special branch in police. The English translation of Bhai aapka knowledge toh kamaal ka hai bhai is boss, you are an intelligent man. The popular use of the Bhai aapka knowledge toh kamaal ka hai bhai meme is to mock someone’s lack of knowledge.
