Order for a dog. Usually to attack at something, or just to growl at it. Commonly used by demons in Supernatural to give orders to Hell hounds.

Attack that; an order you might give a dog so that they will growl, snarl and perhaps bite at the target.

(doorbell rings. you find door-to-door soliciter asking you for money. you thank them kindly and say 'no thanks'. they insist and persist). Turn around and say to Fido "SIC 'EM!"
