This parable has been dated since back in the 1700's as has been documented to have been used as "as a chip off the old block." It is a statement that is frequently used to express that person being said about resembles their biological parents in some way.
-Jenny sure does talk a lot - a real chip off the old block.
-Looking at T Swift's mom - not a real chip off the old block.
-Timmy looks like his mother had a secret affair with someone else besides his father - not a chip off the old block.
Where the "chip" is referring to the son (or sometimes daughter), and the "block" is referring to the father (but seldom the mother). Meaning that the offspring heavily resemble their own parents. Also meaning that the son has acquired a characteristic from their father.

This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
