In the 90's we'd use the word "Rompin" which was another way of saying the F word.
We'd say things like "I'm not rompin !" Kinda scripted but that's what we'd say when serious, though even then saying that would break the ice and lighten the mood.

My personal favorite slang word = Rass.
It's a west indian thing, but I reinvented its use case.
I don't put on a fake accent or anything, I just say things are rass. For example....
Your situation and what you're going through is rass.
Or say someone pulled out some regular car from a garage, but then this car is smoking supercars. The car is rass.
Elon, is rass.
Epstein was rass.
Bugatti is rass.
Ai is rass.
Bill Gates ? Not very popular but still he's rass.
Self made and hit it big ? Big money you're rass. You lose it all, that's rass.
You'd think Chapo is rass. oh yes, he is. I think you're even more rass.
Some of the shit we've seen unfold on this site is rass.
You either say this word at something with wow factor, or it gives a wow factor and people just understand what you mean like a visual. You see a pile up on the freeway. That's rass.
You can say it for people places and things, also events, regardless if it's good or bad. It's a lazy way to say, very good or very bad "Oh that is so rass"
