Are there any one or two crowbars around you? The stir bar is originally just an object. It is a stick that the farmer stirs the manure. The purpose is to mix the precipitated excrement evenly and then use it to water the crops. Originally, the excrement was already smelling bad, and the taste was even worse after stirring.
So I used to use the crowbar to describe people who like to play with the right and wrong, make waves, and make things worse.
