A weaker, smaller person or country that has delusions of being
big and strong and thus tries to
intimidate others by barking constant threats, which usually serve little more purpose than just to annoy all those around. This behavior is often frustratingly tolerated because a violent reaction against such an obviously weaker, smaller person or country would seem immoral and inhumane. Still, sometimes you just want to kick the
fucking thing across the room.
Bill's neighbor constantly argues with him over trivial things, often issuing veiled threats of violence in the process, but Bill never takes the threats seriously as Bill is twice his size and clearly in much better shape. Rather than
going to jail for kicking his neighbor's ass, Bill simply chalks it up to chihuahua syndrome and tries to make the best of the
unfortunate situation.
Did you hear? North Korea is threatening the
United States again. Again? They have such a chihuahua syndrome.
