A cut of meat (usually beef or pork) that has been marinated in antifreeze. Usually given to a neighbor's obnoxious dog that seems to bark all day and night for no apparent reason.
Wife: WTF is that dog barking at now? Its 2:30 in the morning!
Husband: Yeah no shit, this is getting on my last nerve.
Wife: I think we should strongly consider giving that dog a radiator chop in the near future...
Husband: Hells yeah, I'm down.
