To be like a
bull in a china shop is a simile used to describe an extremely rough or dangerous person in a place where gentleness is a must.
It brings to mind the image of a huge rodeo bull exploding into a tiny
curio store and throwing his weight around in a
beserk rage, annihilating every last teacup.
The huge
wrestler burst into the house,
knocking pictures
off the wall like a bull in a china shop.
