One who cuts off a male's testicles.
Her knife sliced, his balls fell to the floor.
(N) A female, so unfathomly ugly in appearance, she causes the immediate decay of the testicles of any man within sight. The Testicles fall away, never to be seen again...
On a scale from 1-to-10, that "girl" was a ZERO. Seriously, I have Zero nads after seeing that Castrator!
