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."That one might be my fault.
We could make it more annoying, by using it in a discussion about jargon. F'rex:
Is a word jargon when it is used to express it's most basic meaning? "Dog" doesn't mean anything special when used by a dog trainer. And, "existing or occurring within the world of a narrative rather than as something external to that world," is the basic definition of the word "diegetic".
(slang is like the opposite of jargon, right?)
