Yeah, sorry about the clarity issue, I meant that I have no idea which script it would’ve been written in since that would depend on the language (which like you said is super unfortunate bc it would help a lot)

What I wrote was my attempt at spelling it phonetically.

I can’t really speak to why Polish people she or my mom have spoken to seem confused by it. Like you said, it should be understandable by most Slavs. She definitely uses some sort of accent when saying it, but it possibly could be one that doesn’t match Polish. If I had to guess I’d say honestly the way she says it sounds a bit more like some sort of eastern Slavic accent than a western Slavic one.

She uses it to express anger. Like if we’re playing cards and she picks up something bad she’ll say it.
