Mom look is the look you get when your boyfriend/girlfriend introduces you to their mom and you see the look of disapproval in her eyes.
Mom look指你男/女朋友把你介紹給他/她媽媽時,你從對方媽媽臉上看到的不滿的表情和眼神。我們稱為“老媽表情”。
For example:
-I think my mom really likes you.....
-Uhhh, no. She totally gave me the mom look....I feel so ashamed.
-我覺得我媽挺喜歡你的…
-才不是呢,看看她的表情就知道了,我覺得好丟臉。
