This is the short form of the phrase "Ignorant Moron".
Also stupid, fool, dip, dunce, brainless, dense, dim, dopey, gullible, half-baked, idiot, irrelevant, out-of-it, obtuse, out-to-lunch, senseless, rash, simpleton, wingnut, thick, witless, and 'tard.
As in, "The guy wasn't just ignorant or a moron. He was a total IGMO!"
