The practice of petty or incompetent criticism; the behavior characteristic of a criticaster.
From criticaster plus -ry, a suffix forming nouns denoting a practice, quality, or set of behaviors (like 'sorcery' or 'mockery'). Rare variant of criticasterism.
Both 'criticasterism' and 'criticastry' describe the same annoying behavior, but 'criticastry' has an older English feel, showing how the language once had multiple ways to mock incompetent critics before standardizing.
