Literary Criticism. Failure to recognize irony, especially due to arrogance, misplaced self-confidence, or a lack of self-awareness.
Origin
Mid 17th century (in an earlier sense). From post-classical Latin alazonia from ancient Greek ἀλαζονεία boastfulness, imposture from ἀλαζονεύεσθαι to make false pretensions, boast + -εία.
