The phrase "be mad for" typically implies a doting or obsessive interest in something. However, there are plenty of antonyms that encompass more negative or indifferent attitudes towards an object or activity. For example, "dislike," "hate," and "abhor" all indicate a strong negative sentiment towards something. "Reject," "dismiss," and "ignore" suggest a more passive disinterest or lack of engagement. Finally, "bored," "indifferent," and "apathetic" convey a lack of excitement, enthusiasm, or passion. Each of these words offers a distinctly different shade of meaning, reflecting a range of attitudes and feelings towards the things that capture our attention - or don't.
