Vultures

If i coud invent an idiom.. i would like to invent one:

''Like vultures circling''

So, what does it mean? Ok, you jolly well know what vultures are don't you? What they eat and such? For you who do not know, they eat fresh carcasses of dead animals. In other words, they eat animals that just died.

So, the thing about vultures, they have a very instinctive way of knowing if an animal will die. And if they do know, they will circle this animal until this animal dies. After this animal blows its last breath, they swoop down, tear the carcass open with their sharp beaks and pull the guts out and consume it with utter greediness and satisfaction.

But the thing about vultures, they are cowards. They never kill an animal unless its dead but yet they prefer fresh carcasses. They will circle the animal as long as it takes, and only attack when the animal is dead. Such cowards.

People with vulture like personas are very dangerous. They look at their victims from a distance, and when they get hungry, they incite others around them with lies and bullshit, so that their victims could die faster. At the end of the day, they gain satisfaction from their victims' loss and laugh (or squawk).

That's my invention. I hope this post could get into Oxford Dictionary and be recognized as a valid literal idiom for the use in formal writings.
