flip
v.— «Not even high-fashion models watch their weight closer than jockeys do. Ideally, a jockey should weigh 112 or less. “A lot of jocks eat, eat, eat and then puke, puke, puke. It becomes habitual with them. We call ‘em flippers, because they’ll stuff down a shake and french fries and then go flip it all up.” (In the toilet area of the jocks’ room, there’s a hand-lettered sign: “No flipping in first two stalls.”)» —“Life on the Fast Track—Each Day, a Jockey Must Wage a Tough Struggled to Keep Ahead of the Rest” by Wayne Johnson Seattle Times July 19, 1985.
