make it rain
v. phr.— «From time to time, patrons flung plumes of cash toward the rafters, letting the dollar bills flutter where they may—a ritual known as “making it rain.” It began as a flashy way for big-timers to tip the dancers, but it has evolved into a thing unto itself—a raw display of wealth and power. In Atlanta, the presence of two or three major rap stars in one club can lead to a rainmaking competition, and leave thousands of dollars on the floor.» —“Naked Hip-Hop Ambition” by Richard Fausset in Atlanta, Georgia Los Angeles Times Apr. 28, 2006.
