聚會(huì)或飯局上低頭看手機(jī)原本是不禮貌的行為，但是隨著越來越多人開始享受這種人群中的“獨(dú)處”，社交時(shí)間也慢慢被“矩形時(shí)間”所蠶食。

Rectangle time is the time of day when people in an obviously social setting instead choose to pull out their smart phones and have some time alone with their "rectangle". The term can also apply to other electronics, such as computers, iPads, etc.
“矩形時(shí)間”指人們?cè)谏缃粓?chǎng)合選擇拿出智能手機(jī)，和自己的“矩形”獨(dú)處的時(shí)間?！熬匦螘r(shí)間”這一短語也可以應(yīng)用于其他電子產(chǎn)品，如電腦、iPad等。

Example:

"Having some rectangle time there, I see," she said to Luke, as he stared at the phone screen while sitting on a scenic beach.
“原來是在享受‘矩形時(shí)間’啊，”她對(duì)坐在風(fēng)光優(yōu)美的海灘上盯著手機(jī)屏幕的盧克說道。
