Unacceptable things

This is the best phrase to use when someone is trespassing your verbal limits. Say it in a firm, projected tone so that you will be heard! Do not laugh when you say it! Do not smile or have a “matter of fact” expression on your face! Do not giggle! Do not use a high pitched voice! Don’t say it as a question, sounding tentative as you go up at the end of the word “unacceptable.” Do not pepper this phrase with filler words such as “like,” “um,” and “you know!” Finally, do not mumble. Draw out your vowels when you speak these three words.
In continuing to let someone know that he has over-stepped his bounds, you can then go on to explain what it was that you didn’t like about what he said to you. Try not to get out of control, screaming and yelling. Instead, talk calmly, yet firmly, so that there is no question that you meant what you said and said what you meant.
Never deviate from what you said!
Therefore, you need to watch out for verbally toxic behavior that someone may once again repeat.
