@auguryignored Mostly I take it as a synonym for "childish." ☺️ I think the Dark Souls version is probably the current poster-child. Warhammer is tricky because Warhammer is, on many levels, aware that it's funny. I think to be grimdark you must be (a) giggle-inducingly infantile but (b) absolutely convinced that you're dead effing serious, tragic, etc.
