It's only "immensely useful" if you seek the solution to a problem that's already been solved (and actually solved, not just happening to share a few keywords with a different problem and thus marked as a duplicate).
If your problem has not yet been solved (especially if it's similar enough to another problem to look like a "duplicate" to someone who does not actually understand the problem), then "trash fire" is hypobolic if anything (is that a word? It should be a word).
This comment is being deleted. Your account is downvoted and restricted from posting additional comments. Reason: "hypobolic" is too similar to "hyperbolic". Next time use the search function and avoid posting redundant comments.
