Our reading
An editorial interpretation.
A blunt threat wrapped in barnyard metaphor. Provoking the bull stands for testing authority, while the horns represent swift, painful consequence. The phrase channels old folk warning into a menacing, almost theatrical scolding aimed at discouraging further defiance.
