The phrase "made waves" is often used to describe someone or something that has caused a significant impact or disruption. However, there are many antonyms that can be used to describe the opposite of making waves. Some examples include "blending in," "fading into the background," "keeping a low profile," and "maintaining the status quo." These antonyms depict a person or thing that does not cause a stir or draw attention to itself. Instead, they suggest a more subdued or unremarkable presence. While making waves can be beneficial in some situations, there are certainly times when blending in or maintaining the status quo is more appropriate.
