pre-joint: as one is doing the preparations or actions of rolling a joint, they encounter a diminutive amount marijuana residue on their fingers.
post-joint: after one, or a group has successfully smoked and passed around a joint, they may realize their fingers have a sticky marijuana residue, that may even have a slightly odorous resonating smell.
"No, I can't do that right now, I have doobiefingers."
"And then I tried to wipe my hands #doobiefingers'"
"Man, I can't even type anymore because of these doobiefingers."
