Off the hip is a colloquial expression that refers to an impulsive, spontaneous action or remark. The antonyms for this phrase could be calculated, premeditated, or deliberate. When someone takes a calculated approach to a situation, they make decisions thoughtfully and with careful consideration of all factors involved. Premeditated actions or remarks are planned in advance, with the intention of achieving a specific outcome. Deliberate actions, on the other hand, are purposeful and intentional, not impulsive. Opposite of off the hip, these antonyms suggest a more cautious, thoughtful approach to decision-making and communication.
