What is a disrespectful or scornfully abusive remark or act called?

little b, I’m not surprised.

prunes are old lady grapes! ( ok don't tell anyone y'all but. I actually love prunes! that would ruin my rep if my friends now that I like prunes so don't tell anyone! and hey I take the insult back! I love prunes! and they're not old lady grapes sorry y'all!) yes I take my insult back!
