sailboat fuel
n.— «In perhaps the ultimate example of military capitalism, KBR reportedly ran convoys of empty trucks back and forth across the insurgent-laden desert, pointlessly risking the lives of soldiers and drivers so the company could charge the taxpayer for its phantom deliveries. Truckers for KBR, knowing full well that the trips were bullshit, derisively referred to their cargo as “sailboat fuel.”» —“The Great Iraq Swindle” Rolling Stone Aug. 23, 2007.
