Improvised Fucktard Device. A fiendishly stupid trap left by a fucktard that is easy to overlook because it doesn't look like a threat to life or limb or your ego. If it doesn't kill you it just leaves you wondering who's the bigger dummy, the fucktard who set it, or you for blundering into it.
The old flaming bag of dog poo is an IFD that never goes out of style.
