A Ganguli is a Person who is really lovely and outstanding, but keeps her real emotions hidden..he/she is the center of the friend group and makes everyone feel happy...
A street term blending "gang" and "mafioso," referring to someone deeply connected and loyal to their crew or gang. A ganguloso is trusted to hold it down and keep things solid within the group, much like a made man in a mafia family.
Tony’s been with us through thick and thin. He's a true ganguloso, you can count on him no matter what.
