Literal Translation: Nothing in the butt, yet has gone to defecate Juhu. For those unfamiliar with the landscape of Mumbai, Juhu is a popular beachside destination which is a paradox all by itself. Classy high street boutiques exist side by side with humble vada-pav and pain-puri wallahs. It also takes a considerable amount of 'goo' (poop) to defecate the entire Juhu area. Therefore, this gem of a phrase can imply that a person doesn't have the capacity to do a task despite their loud proclamations.
Student A: Did you hear? She is applying to foreign universities like Haarvard and Gambridge!
Student B: With only 60%? Gaand mein nahi hai goo, hugne chale hai Juhu!
