Bangalore is a city in India.
Bangalored refers to people who have been laid off from a multinational because their job has been moved to India.
Bangalore is cited in particular because of its reputation in the USA as a high-tech city.
It may not be entirely correct for dictionaries to verbalise outsourcing to India as Bangalored! India’s other cities Delhi, Chennai, Mumbai also attracting call centres ... the Americans could perhaps also talk in terms of their jobs being “Delhi-ted” "Chennaied" "Mumbaied"
American IT sectors are in the process of being Bangalored.
