Being knee deep in something refers to being deeply involved or immersed in a particular situation or activity. Its antonyms would include detachment, disconnection, aloofness, and remoteness, where one tends to be emotionally or physically distant from a situation, avoiding deep involvement. Another possible antonym is superficiality, where one engages in an activity or a situation without any depth, meaning or seriousness. Other antonyms include ignorance, unawareness or unawareness, where one is completely oblivious or uninformed about a situation or activity. Whether it is detachment or superficiality, being knee deep in something is the opposite and indicates a level of engagement that goes beyond a surface-level involvement.
