IEC's are used by our friends in the funny hats... They are not quite as complex as IED's (Improvised Explosive Device) which is used by our friends in the middle east, because the funny hat people dont have the technological advancements yet. If you were to ever get in your car and an IEC went of, possible side effects include rashes, funny smell, and death.
Muslim 1 - "Holy Sh*t dude! That Durga just blew up an Improvised Explosive Curry bomb. Allah! If they start using those on us we have no chance of our Jihad raids."
Muslim 2 - "Too bad we don't know how to use curry like that."
