喝醉了还能回家是因为“啤酒指南针”

　　有些醉酒高手在喝醉之后不用人送也能自己找到家，但是第二天他可能完全不记得自己是怎么回家的。所以有人开玩笑说，这些人脑子里一定有个隐形的指南针。

　　Beer compass refers to the invisible device that ensures your safe arrival home after a booze cruise, even though you're too pissed to remember where you live, how you get there, and where you've come from. It seems that there is a beer compass in your head that can get you back at home without even remembering it。

　　啤酒指南针(beer compass)指喝得酩酊大醉之后还能让你安全回到家的一种无形的指路设备，你可能醉得连住在哪里、怎么回家的以及从哪里回的家都不记得。好像你脑中有一个啤酒指南针，能够让你在断片的情况下回到家里。

　　Example

　　I can't believe I made it back to my new flat the other night, I've only just learned the bus route into town when I'm sober. Must have been the beer compass…

　　我真不敢相信，那天晚上(喝醉酒了)我还可以自己回到我的新公寓。我只是在没喝醉的时候看了看乘车路线而已。我的脑子里一定有个“啤酒指南针”。
