A spliff-joint attached to the end of a blunt, creating a smoking experience that transitions from joint to spliff to blunt. Can be quite large, and typically require a number of folks to finish.
You wanna smoke a jiffy-blunt? I just got all this dank bud and wanna role it up for everyone

Yeah man, that sounds dope. I'll roll the spliff-joint, you role the blunt.

Indeed, we did win sectionals.
