The phrase "hooked in" typically describes a state of fascination, attraction, or addiction. However, there are various antonyms that can accurately express the opposite of being "hooked in". These antonyms include words such as disinterested, detached, aloof, unimpressed, uninterested, and apathetic. Instead of being fascinated or attracted to something, these antonyms describe a state of being unmoved, uninvolved, or indifferent to it. They suggest a lack of emotional or intellectual engagement and indicate that the person is not invested in the subject at hand. So, when someone is not "hooked in", they may feel disinterested or detached towards the situation.
