Fallacies and figures of stupidity.
Knowing a bit of logic gives you a powerful source of rebuttals. But in rhetorical argument, some fouls in pure logic — such as ad hominem — fall in bounds. In fact, the only real intentional fouls in rhetoric comprise any argument that stops an argument, through fighting or distraction. Then there are the unintentional fouls, for which the proper Homer Simpson term is, "D’oh!"
