a can of whoopass

A phrase used to indicate that the target is about to be introduced to a whole world of pain. Specifically, you, by opening this can, are going to unleash the power of whooping (that is, in the sense of attacking and beating, not in the sense of whooping cough) upon their sorry ass.
