Here's how it evolved:
* "Set 'em" was originally used in the context of hunting, where it meant to release a dog to pursue and catch prey.
* "Sic 'em" became a more common and casual version of "set 'em" over time, and it came to be used to command a dog to attack a person or animal.
It's important to note that:
* "Sic 'em" is a dangerous command. It encourages aggressive behavior in dogs and can lead to serious injuries or even death.
* It is never acceptable to incite a dog to attack another person or animal. Responsible dog owners should train their dogs to be obedient and non-aggressive.
If you hear someone say "sic 'em," it's important to be aware of the potential danger and take appropriate precautions.
