someone who ignores the person that they are with and gives attention to their mobile phone instead

Do you get annoyed at phubbers who look at their phone instead of you? 你对那些只顾看手机而不是看你的人感到恼火吗？

I’m not a phubber. In fact, last night the whole family sat together around the dinner table in friendly conversation. 我不会只顾看手机而忽视身边人。事实上，昨晚全家人一起围坐在餐桌前聊得很开心。
