Well, these terms do make things easier if the person you're talking to actually knows what these fancy words even mean. I'm generally of the opinion that using such labels for fallacies (sans the common ones that everyone already should know like strawman, ad hominem, etc.) is lazy and, in a sense, condescending. In the end, nothing beats taking the trouble of explaining exactly why an argument is invalid or not.

My main beef with this is that it makes the practice of debate look like something reserved for philosophy or law majors when practically anyone with a decent grasp of their reasoning capabilities can participate in it. In all honesty, I don't like the term "debate" either because it simplifies an argument into a dichotomy, leaving little room for compromise between either side... though that's a different matter altogether.
