開(kāi)大會(huì)的時(shí)候、腦子里想事兒的時(shí)候，我們很多人都會(huì)無(wú)意識(shí)地上下按動(dòng)手里的伸縮筆筆帽按鈕，似乎那個(gè)“咔咔”的聲音能夠幫我們解悶兒或者讓我們更加專(zhuān)注。

Push pen anxiety is a psychological state characterized by one's excessive push-in push-out of his or her retractable pen, often due to stress or boredom. It is addicting because of its sound and its motion of going up and down. You kind of get hypnotized.
“按筆焦慮癥”描述的是一種心理狀態(tài)，就是在無(wú)聊或者壓力大的情況下不停地按動(dòng)伸縮筆的筆帽按鈕。這種按動(dòng)發(fā)出的聲音和上下伸縮的動(dòng)作會(huì)有點(diǎn)讓人上癮，可能會(huì)讓你沉迷其中。

For example:

That kid at the back of the class has a serious case of push pen anxiety. He has been pushing his pen button for nearly half an hour.
班里坐最后一排的那個(gè)孩子有嚴(yán)重的按筆焦慮癥，他已經(jīng)連續(xù)按動(dòng)那個(gè)筆帽按鈕半個(gè)小時(shí)了。
