A racist name for a white person. Implying that their ancestors were feeble/ignoramus beings that took shelter in a cave. Thus resulting in their lack of pigmentation in skin and lightly colored eyes.
Bill: " I went to a party on the North Side last night and everybody was giving me weird looks!"
Dick: "What are you doing hanging out with those cave dwellers anyway? They really get under my skin."
