No, it would sound ridiculous.

Yup. Even my (straight) best friend uses 'Yaaaassss' now when something awesome happens.

Only via texts though, or semi-mockingly in speach. Would never have a serious conversation using those words.

Just with my close friends because I think it's hilarious. They've started saying a few of them too.

Well me and friends all say "yaaass" and "slayy" but mostly just for fun, "yaaas" has gotten out of control though

Me and my (literal) sis say "Yassss bish" all the time.

ofc no, it's embarassing for me as a straight man

I say YASSS or YASSS bitch with certain friends, but I don't scream it like I do online

If I wanted to say that words it wouldn't be possible, the only word I can translate would be slay but it's not the same.
If I lived in USA, Uk or Australia I would use yaasss and slay.
