I’ve only heard this said by Indian people, so I’ve been assuming that when I see it written online it’s Indians. Per that link it looks like all over the US it’s at least occasionally used. That’s crazy, and I can’t stand it; hopefully this doesn’t become standard.
Onomatopoeia, it’s a fun word on it’s own, but I love the while idea of it. Especially in other languages, like the million different words for dog barks.
