slang A woman who rejects, dismisses, or is ambivalent toward sexism, misogyny, or male chauvinism. Some of my more feminist friends accuse me of being a chill girl just because I don't fly into a rage every time a man makes some diminishing comment about women. During college, I considered myself to be something of a chill girl, but when I entered into business, I saw just how pervasive sexism really is.
