In Greek mythology, the lotus-eaters (Greek: λωτοφάγοι, translit. lōtophágoi) were a race of people living on an island dominated by the lotus tree, a plant whose botanical identity is uncertain. The lotus fruits and flowers were the primary food of the island and were a narcotic, causing the inhabitants to sleep in peaceful apathy. After they ate the lotus, they would forget their home and loved ones and long only to stay with their fellow lotus-eaters. Those who ate the plant never cared to report or return.
Figuratively, 'lotus-eaters' denotes "people who spend their time indulging in pleasure and luxury rather than dealing with practical concerns".
