A person who engages in stage-phoning is someone who talks loudly on their mobile in a deliberate attempt to attract the interest and attention of people around them. Such individuals appear to be behaving as if they were giving a performance, with the mobile as a theatrical¹ prop², hence the use of the word stage.

Stage-phoning（演戏式通话）指一个人用手机打电话很大声，故意想要吸引旁边人的关注。这些人打电话时候的行为就好像在表演一样，把手机当作道具，所以才会用stage这个词来表示。

The derived³ noun stage-phoner has been coined to describe these types, who in American English are sometimes also referred to by the rather derogatory term cell (phone) jerk. We meet stage-phoners at every street corner, waiting room or café.

由此衍生的stage-phoner就指进行演戏式通话的人，在美式英语中还有一个更具贬义的词cell (phone) jerk（手机傻冒）来形容这些人。在街角、等候室或者咖啡馆都会有他们的身影。
