It is more about its sudden ubiquity. When I see it constantly peppered into posts by folks who have never used it before, I think, "Sus."
I don't know why you find it suspicious. Suddenly, folks have a word for a thing that means only that thing, and they start to use it for that thing, in discussions about that thing.
I find it an interesting example of observable language spread. Kind of neat, honestly.
(slang is like the opposite of jargon, right?)
Almost entirely not, no.
