(adj.) Exhibiting an extreme and baffling degree of unintelligence, often appearing as a profound blankness of thought or an inability to comprehend basic ideas, rendering
one speechless or prone to exceptionally foolish actions. More
intense than merely stupid, it encapsulates a comprehensive
mental dullness.
