As onimoniapia this word is the sound a loud gun makes. It is used as a verb to describe the besting, killing or defeating of something usually in some competitive environment.

The literal definition is to shoot/hit something living so hard and in such a way that the body above the waist is blown into bits while the waist down remains mostly intact. It can be used in slang terms to describe any kind of violent killing however and as an onomonopia in the same situations.
