Chihuahua syndrome

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.
