The phrase "am in cahoots" refers to a situation where one is collaborating or conspiring with someone else for a common goal or purpose. The antonyms for this phrase are words that describe the opposite of this situation, such as opposing, diffident, independent, antagonistic, and uncooperative. When someone is opposing the actions or ideas of another, they are not in cahoots. When someone is diffident, they lack the confidence and assurance to participate in a collaborative effort. Independent individuals do not rely on others for support, and therefore cannot be in cahoots. Antagonistic people are hostile or opposed to others, making it impossible to collaborate or conspire. Similarly, uncooperative people do not work well with others and are unlikely to be involved in a cahoots situation.
