"Pling" seems to be uniquely British, with usage sometimes documented as in the Commonwealth countries too. Its actual origin seems to have been within Acorn Computers, and thus spread mostly to countries where Acorn computers were sold in any numbers, which notably does not include the USA. On Acorn computers, application bundles are directories prefixed with a Pling, so the Paint application is called "!Paint", pronounced, "Pling Paint", for example.
