“There are six things the Lord hates, — seven that are an abomination to him: : haughty eyes, a lying tongue, hands that shed innocent blood, a heart that devises wicked plans, feet that make haste to run to evil, a false witness who breathes out lies, and one who sows discord among brothers.” - Proverbs 6:16–19 (ESV)

The recommendations made for disciplining for a rude and disrespectful teen is, after affirming love for the teen, explain to him what happened, why it was wrong and call for an admission of guilt. Confront him. Enforce a consequence if necessary.

"Teach your teen what disrespect looks like. Make it very clear what you expect from him. Define it, using a reasonable voice, possibly using a time together when you or he is not angry. Make it a reasonable discussion. Then, even after being clear, know that your teen will test your limits because it is the nature of teens to do so. When the limit is breached, follow through with appropriate consequences." - Dr. John Townsend, Boundaries with Teens
