A funny way of saying "whole family"
a group of people living or working together or in close proximity, who have intimate relationships. Sometimes, it is used ironically.
This expression dates back to at least 1621 in the form of “chip of the same block” when it appeared in Sermons by Robert Sanderson, the Bishop of Lincoln, “Am I not a child of the same Adam, a chip of the same block, with him?” The “block” in question may have been of stone or wood. Not much late, John Milton was one of the first to be credited with the change to “old block” in Apology for Smectymnuus (1642). The change to “chip off the old block” only happened much later during the 19th century.
