不知道你有沒有注意過公交車上人們的表情？不論他們是在低頭玩手機，還是看窗外，或是看別人的包包或鞋子，表情幾乎是清一色的漠然，這就是bus look——公車表情。這個表達也適用于地鐵，不過英文就該改成subway look了。

Bus look refers to a blank facial expression (somewhat similar to a poker face) used while riding a bus. A person sustaining a bus look is often in deep thought or examining the surrounding people. Off the bus, this can be considered acting Stoic.

“公車表情”指的是在乘公交車時臉上顯露出的漠然的表情（有點像面無表情的“撲克臉”）。一個擺出“公車表情”的人通常是陷入深思或是在觀察周圍的人。如果下了車還是這副表情，那么這個人大概就會被視為禁欲主義者了。

Example:

I stepped on the bus and looked down the aisle, all I saw were a bunch of people with bus looks minding their own business.

我上車后向另一頭望去，看到的都是些擺出“公車表情”、忙著各自事情的人。
