There are several antonyms for the word "osmosed," which means to absorb or take in knowledge or ideas. One possible antonym is "repulsed," meaning to reject or resist something. Another antonym might be "ignored," which means to pay no attention to a particular subject or concept. Instead of osmosing information, one could also be "ignorant," or lacking knowledge about a particular topic. Similarly, one could be "oblivious," or unaware of a concept or idea.
