Agnosticism is mostly just Reddit intellectualism.
Perhaps just in this very unfortunate moment of time. Another poster correctly noted the term has been around a long time. I looked it up and the term was coined by Thomas Henry Huxley in 1869 or 1870, depending on the source. The term is a lot newer than I would have guessed, but it has been around for well over a century.
if I called myself a madeup word
It was a made up word in 1869-1870.
In reviewing some of the other comments, it seems the reddit factor plays large. I am not religious myself. I am an atheist-agnostic (I oscillate between the two as I reflect on the evidence against any organized religion in the modern world that has any sway). I really hate the American, super-redditor brand of atheism/agnosticism that is far left, intellectually vapid, and utterly embarrassing. When I tell others I am not religious or atheist, these far left associations take their toll. A lot of the hard right in Europe were atheists or at the very least very critical of Christianity, and not without good reason. I will also say as bad as left-wing, American atheists/agnostics are, bible thumpers are no less endearing to me, at least for the most part.
If anyone here has read either Decartes or Heinlein's Job: Comedy of Justice as just two examples, they will see the importance of making the distinction between agnosticism and atheism, As much as reason and evidence and modern science not yet ideologically corrupted persuade me there is no God and certainly no afterlife, there is no way of knowing that is absolutely, positively so. On the other hand, we have to use the tools we have, as limited as they are. Yes everything could be a simulation or a malicious god (or aliens) or the Matrix tricking us to think our perceived reality is an induced illusion, but the probabilities are incredibly low.
