Yes, "raise eyebrows" is an idiom! It means to bring attention to something in a negative way. It means to cause surprise, shock, or offence. Ex: Dropping out of college will certainly raise some eyebrows in my family. Ex: You don't want to raise any eyebrows around here by playing music loud at night. Ex: Victoria's new pink hair will raise a few eyebrows at school. Ex: Geoffs sudden marriage to Jean raised a few eyebrows. Ex: The headline this morning made Pete raise an eyebrow.
