Apologize to the person that you cussed out by clearly stating that you are sorry for the language and tone that you used while addressing him. Even though you may feel that part of your tirade was justified, avoid offering any explanations or excuses, because these will weaken the sincerity of your apology. Clearly state that you are sorry and specifically state what you are sorry for. Failure to include both these elements in your apology will make your apology seem insincere or flippant.

Ask the person to forgive you for having cussed her out. Although you cannot take your words back, by asking the person to forgive you for your actions, you are letting her know that you acknowledge having done wrong and that you value your relationship with her. Asking for forgiveness lets the person know that you wish to restore your relationship and mend hurt feelings.

Make an attempt to understand how your tongue lashing may have made the other person feel. Did you use particularly hurtful or hate-fueled words? By understanding how the other person is feeling, you will be able to specifically tailor your apology to the situation and to his feelings. Acknowledging and validating his feelings in the process of apologizing will make your apology more sincere and will make it easier for him to accept the apology.

Offer to make some kind of restitution. Offers of compensation are most successful when they are closely connected to the offense. Although you cannot take your words back, you may be able to rectify some consequences of your words. For example, if you cussed the person out in front of others, you may offer to clear the person's name so that the witnesses understand that you regret your choice of words.
