喝醉了還能回家是因為“啤酒指南針”

　　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記得自己是怎么回家的。所以有人開玩笑說，這些人腦子里一定有個隱形的指南針。

　　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.

　　啤酒指南針（beer compass）指喝得酩酊大醉之后還能讓你安全回到家的一種無形的指路設備，你可能醉得連住在哪里、怎么回家的以及從哪里回的家都不記得。好像你腦中有一個啤酒指南針，能夠讓你在斷片的情況下回到家里。

　　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）我還可以自己回到我的新公寓。我只是在沒喝醉的時候看了看乘車路線而已。我的腦子里一定有個“啤酒指南針”。
