Sloppy logic; a wordplay on the term fellatio, "fallacio" refers to an argument so patently based on false premises and defended with fallacious thinking, even a fool would know it sucks.
"Your defense of your point, which consisted of ad-hominem and strawman arguments, demonizing, and refutation by ridicule, was an obvious example of fallacio."
