閒暇時光要如何度過呢？有人邀約不斷，忙於應付；有人卻嫌時間太多，不知怎麼打發。還好我們居住的地方周邊一般都會有商場，在家裏無趣的人們可以偶爾選擇去那裏打發時間，做個mall rat。
Mall ratrefers to youngsters that spend time at the mall just to hang out whenever they get the chance with no other particular purpose.
Mall rat指一有空就喜歡到商場裏漫無目的閒逛的年輕人，我們姑且簡稱為“貿鼠”。
These youngsters walk around the mall for hours at a time, and usually do not make one single purchase. These creatures think they are "cool" and will find someone to mate with by wearing slutty clothes, but in reality, they are just wasting their life away walking around the mall all day long with nothing better to do.
這些年輕人能在商場裏逛數小時，而且通常什麼都不買。他們覺得穿著性感時髦的衣服在商場裏走很“酷”，並且希望能在那裏遇到跟自己相配的另一半。其實，他們這樣做只是在浪費生命，一無是處。
For example:
I used to be a typical mall rat hanging around watching the crowds, especially the girls. But now I join the football club, and I have no time.
我過去特喜歡在商場閒逛，在那裏看人來人往，主要是看女孩子。但是現在我加入了足球俱樂部，就沒時間了。
