curt

This word describes a specific kind of brevity that feels like a social slap. It is not merely being concise for the sake of efficiency, but rather a deliberate stripping away of politeness to signal annoyance, superiority, or a desire to end a conversation immediately. It carries a sharp, cold energy. While a concise person is seen as efficient, a curt person is perceived as hostile. It is most frequently used in professional or formal settings where the expected social lubrication of small talk is suddenly and jarringly removed, leaving the recipient feeling slighted or rebuked.
