Imbecilicus Argumenticus

An absolutely idiotic, half-baked, utterly stupid and often hypocritical argument that makes you look like a meathead.

"I think the death penalty is good, even if it does kill innocent people now and again. I think anyone who kills an innocent person is a murderer and deserves the death penalty."

It doesn't get any more imbecilicus argumenticus than that.
