suckle your drip
To ingest the drip of another person who has snorted drugs in an attempt to gain at least some mild buzz from that drug. It is a technique used only if the person will not give you any of the drug itself.
Person A: "Man Jody is all blown up.. look at him, but he says he's out."
Person B: "Hey Jody, can I suckle your drip?"
Jody (sheepishly): "Oh, come on guys!"
Person B: "Hey Jody, can I suckle your drip?"
