The satirical term mocking the annoying cold caller telesales people and companies involved who outsource western based companies call centres to India as a money saving practice.

These call centres will often ring you up uninvited and attempt to sell you a product, such as an internet service even though they don't have a firm grasp of the English language.

The phrase can also be attributed to the UK television show Fonejacker, who impersonates such a person as a prank caller.
