Foiley
The 'loose' (usually sitting on a bed or coffee table) foil or tray that is already 'set' (already has a piece of heroin, etc, on it.)
Matias: "Can you pass that foiley?"
Ananda: " . . . That's my foiley. You already smoked all yours."
Matias: "That's bullshit."
Ananda: " . . . That's my foiley. You already smoked all yours."
Matias: "That's bullshit."
