You: Something is falling from the Russianjet.
Person: It's a bomb you imbicile!

A cross between an imbecile and an idiot. This word only comes out when you're so aggrevated with someone that you try to call them one or the other and both come out as this glorious term. (Not to be confused with the much lamer term of Stupidiot)
