A "thickhead" is a derogatory term for someone considered unintelligent or foolish. ðĪŠ It implies a lack of common sense or an inability to understand simple things. Think of it as the opposite of being sharp or quick-witted. It's like calling someone a brick wall â not much gets through. A thickhead might consistently make obvious mistakes or struggle with basic concepts. It's not a nice thing to call someone, as it directly insults their intelligence.
