IED most often means “improvised explosive device,” a bomb that is homemade rather than produced and deployed through regular military channels. In mental‑health or forum contexts, IED can also mean “intermittent explosive disorder,” a psychiatric condition involving repeated episodes of sudden, intense anger that are out of proportion to the situation.

Main meanings of “IED”

  • Improvised explosive device (bomb)
    • A homemade or improvised bomb, often assembled from whatever materials are available (for example, artillery shells, fertilizer-based explosives, or commercial explosives).
* Commonly associated with guerrilla warfare, terrorism, or insurgent attacks, including roadside bombs or car bombs aimed at vehicles, buildings, or groups of people.
  • Intermittent explosive disorder (mental health)
    • A diagnosed mental health disorder where a person has repeated, impulsive outbursts of verbal or physical aggression that are far more intense than the trigger would normally justify.
* These episodes tend to be brief but can seriously damage relationships, work, and reputation, and may require therapy and sometimes medication as treatment.

Other less common uses

  • In technical or reference contexts, IED can also stand for things like “intelligent electronic device” in power systems or titles of certain etymological dictionaries , but these are much less common in everyday conversation.

If your question is about safety, violence, or harm (for example, bombs or intense anger), it is important to stay safe and contact local authorities or a mental health professional rather than trying to handle it alone.
