What does to put something down a notch or two mean?
I'm not a teacher.
I know the meaning of the following idiom:
Take down a notch = take down a peg = deflate or humble someone, as in:
He’s so arrogant that I wish someone would take him down a notch.
That defeat take them down a peg.
The idiom in question “to put (take, or pull, or bring) down a notch (peg) or two means to lower someone’s high opinion of themselves.
Both notch and peg in these idioms allude to a series, the former of indentations, the latter of knobs, used to raise or lower something. Specifically, peg alludes to the pegs used to lower a ship’s color.
