Seeing the rival company's market share, he was drooling with envy.
Tips
history
Built from earlier images of drool: 唐·柳宗元《招海贾文》 "垂涎闪舌" and 宋·苏轼《将之湖州》 "未去先说馋涎垂". The four-character form crystallized later as 馋涎欲滴 — "the drool is about to drip".
usage
Works literally for tasty food and figuratively for any object of greedy desire (money, market share, a job offer). Stronger and more vivid than plain 流口水.
