@izzythepush,
Yes it is. It's ignoring the content of my arguments, and saying I'm a liar. The easiest, cheapest way for a person to avoid debate of issues.
Ad hominem (Latin for "to the man" or "to the person"), short for argumentum ad hominem, is where an argument is rebutted by attacking the character, motive, or other attribute of the person making the argument, or persons associated with the argument, rather than attacking the substance of the argument itself.
