a cross between a dipshit and an idiot. when one or the other doesn't do the moron justice, you put them both together for a fitting adjective for your challenged friend.
The type of person who is at all times the dumbest person in the room.
It's guaranteed that if this person opens their mouth, something stupid will be said.
Can you believe what that dipshidiot said? I've never heard anything that stupid in my entire life!
Complete moron or imbecile. One who performs foolishly in public on a regular basis, blissfully ignorant of the fact he is a professional horse's ass. Typically applied to Internet activities such as social networking sites, but may be properly used to describe politicians and elected officials, and certain celebrities. Never used in a complimentary sense, but may be used in jest to roast a friend's chestnuts, particularly after a round of drinking. See also: "Shit for brains."
It was bad enough he has been sleeping with my wife, now that dipshidiot wants me to fertilize his crops in Farmville!
