budget dust
n.— «It seems strange to talk about $30 million here and there as mere budget dust—as the budget writers call it. But in the state’s $23 billion budget, $30 million is a bit like the loose change you find under your sofa cushions.» —“In state spending, hot-button items amount to mere ‘budget dust’” by Rebecca Cook in Olympia, Wash. AP Dec. 29, 2002. (source: Double-Tongued Dictionary)
