Gauranga (Gouranga) was a nickname of Sri Caitanya Mahaprabhu, a monk in India who 500 years ago (sorta) founded the Hare Krishna sect.
There were lots of "GOURANGA!" posters in Scotland in the 70's and spam still goes around now. They just want people to be happy!
Call out Gouranga be happy!!!
Gouranga Gouranga Gouranga ....
