Is there any dialect of English that uses "positive ever" to mean "once"?

Solution 1:

Not really an answer but too long for a comment so typing here, apologies.

I use that structure even though I know it is wrong. However, I use it in specific situations with a meaning similar to;

Yes, I do study for my exams. I am not playing games all day!

I use positive ever to emphasize and with the meaning once or more. I use it in a sentences when I have done (or pretend to have done) something mischievous. Like;

Have you ever been to a love hotel? -averting eyes- Umm... Yeeeeees, I have ever been to a love hotel (with a stronger emphasis on ever).

This above is a real conversation I experienced recently in Japan. However, I know this is something my evil mind produced to play with others' minds. It has nothing to do with my dialect or whatever.
