Well then you probably picked it up from us, I'm pretty sure. The spasmodic overuse of "really" is a very recent thing here, but its DEEPLY entrenched. Its depressing to think its taken over in the land of...wherever you live.
At first it reminded me of â€ほんとですか？†as it is so often translated monotonously in 1980s anime dubs as "What's that? Is it really true!?". Then that charm wore of and its more grating than the previous decade's horrible linguistic defect; ending all of your sentences in "so..." as to imply a sort of off camera meaning or substance that was missing from the rest of the user's sentence (or paragraph, or day, or year, or life).
EDIT: Just saw another annoying used of "really?" only seconds after posting this:
Specifically called out in parenthesis, in a way you would do with nothing else I can think of. WTF? Its mass dementia, I tell you.
I feel like someone went back in time to hunt dinosaurs, stepped on a butterfly during the trip, and it instantly and permanently effected the English language...and I'm the only one who realizes it.
