The meaning of "Ad hominem" is against the man, is a fallacy that is also known as the personal attack fallacy or name-calling fallacy. This kind of mistake happens when someone criticises the speaker rather than the argument.
An example of "Ad hominem":
Sam: I believe that we ought to reevaluate how the federal budget is allocated by the government.
John: You should just leave the country and relocate somewhere else if you can't be loyal and support how your government decides to use taxes.
