From The Word–NIV Translation–the fool is described mostly in Proverbs.
The proverbs of Solomon: A wise son brings joy to his father, but a foolish son brings grief to his mother. Proverbs 10:1
The wise in heart accept commands, but a chattering fool comes to ruin. Whoever walks in integrity walks securely, but whoever takes crooked paths will be found out.Whoever winks maliciously causes grief, and a chattering fool comes to ruin. The mouth of the righteous is a fountain of life, but the mouth of the wicked conceals violence. Hatred stirs up conflict, but love covers over all wrongs.Wisdom is found on the lips of the discerning, but a rod is for the back of one who has no sense. The wise store up knowledge, but the mouth of a fool invites ruin. Proverbs 10:8-14
Whoever heeds discipline shows the way to life, but whoever ignores correction leads others astray.Whoever conceals hatred with lying lips and spreads slander is a fool. Proverbs 10:17,18
The lips of the righteous nourish many, but fools die for lack of sense. 10:21
A fool finds pleasure in wicked schemes, but a person of understanding delights in wisdom. 10:23
Stay away from a fool, for you will not find knowledge on their lips. 14:7
The wise fear the LORD and shun evil, but a fool is hotheaded and yet feels secure. 14:16
The tongue of the wise adorns knowledge, but the mouth of the fool gushes folly. 15:2
The discerning heart seeks knowledge, but the mouth of a fool feeds on folly. 15:14
Eloquent lips are unsuited to a godless fool— how much worse lying lips to a ruler! 17:7
It is to one’s honor to avoid strife, but every fool is quick to quarrel. 20:3
Answer a fool according to his folly, or he will be wise in his own eyes. 26:5
“If you play the fool and exalt yourself, or if you plan evil, clap your hand over your mouth!” 30:32
No longer will the fool be called noble nor the scoundrel be highly respected. Isaiah 32:5
In this self-confident boasting I am not talking as the Lord would, but as a fool.2 Corinthians 11:17

The fool’s mouth always identifies him.
The fool’s insecurity is evident in their paranoid behavior.
The fool will always boast of himself–self-congratulatory–always patting self on the back.

The fool never believes that others can see through their foolishness.
The fool thinks they have a right to dictate to others.
The fool is blinded to truth because their ego is the driving force in their lives.
The fool always needs someone else to clean up the messes they make.
The fool never accepts responsibility for what they do and always blames others when things go wrong.
The fool never listens to those who are wise because they don’t believe anyone is wiser than they are.
