俗話說，人要是走霉運，喝涼水也會塞牙。如果你發現最近特別背，干什么事都不順，那大概是brown touch（棕手指）找上你了。

The brown touch is similar to the Midas touch, but instead of everything they touch turning to gold, it becomes worthless.

“棕手指”和“金手指”很像，只不過“金手指”是點石成金，而“棕手指”則是點金成土。

Example:

Mike's wrecked his third car in a year and lost his job and his girl. He's got the brown touch.

這是麥克一年內撞毀的第三輛車了，今年他不但丟了工作還被女朋友甩了。他被倒霉的“棕手指”纏住了。
