I think you mean ad hominem.

http://en.wikipedia.org/wiki/Ad_hominem

Wiki has it about right for all practical purposes, but defines terms slightly different from its origin of Arthur Schopenhauers "Eristic Dialectics". Btw most of it actually originates from Aristote (Topica V, Organon). To fully understand the concept there is probably no way around reading the whole context in these sources. I'd guess both are available in english translations.
