It is a highly murdered version of the phrase 'Hold it', used commonly by bus conductors in Bangalore to indicate to the bus driver to stop the bus.
1. Bus conductor to driver : Wolden !!! (Bus stops, passengers alight) Rayya, rayya, rayya !!!
2. Bus conductor to driver : Reverse, reverse, innu swalpa (little more in Kannada), (whistle screeches) wolden !!!
