A junky slang term for injecting heroin. Duck hunting = shooting = injecting heroin. Often used when two colluding heroin users wish to speak of their habit without the third party being aware.
ie:
Person A: "Are you going duck hunting tonight?"
Person B: "Sure am. Wanna tag along?"
Person A: "Yeah, it'll be great. I'll bring some money."
Person C: "What the fuck are you two talking about?"
