“不见不散”用英语怎么说?

建议把你的理解"见了就散"改为"见了才散",强调是见了面以后才散开,不是在乎见面的时间的长短,说这句的时候主要是为了赴约,你说你能确定未知的约会的长短吗?
就是要相见,别的一无所求,强调的是执着.
就算是"见了就散",也是履行之前的相见诺言了~

square是守旧的含义;
be there or be square字面意思是"要么去参加,否则你就落伍了"
一般用于在邀请某人参加某个活动的时候说.(当然中文意译过来就是"不见不散")
而且对象是朋友,因为这个说法很是casual.
eg:
A:How about coffee?Usual time and place?
B:Be there or be square!

Hmmm...let me see...oh,i know.Ge You,the actor in the movie "Be there or Be square" said,"i can see,i can see again!this is the power of love.So it is,I see.Where is my honey?"

I see!I can see again!This is the power of love!So it is.I know!Where's my dear?

正如楼上所说,孙楠唱得没错.
不见不散：Be there or be square.
A 'square' is a person who is ordinary or conservative in behavior or demeanor,not 'cool' or 'in.' The writer is saying that if you are not part of the scene or the action,then you are not cool.I think this is relatively new in usage,but I am unsure of the origin.
Immediately after World War II the word "square," which had long meant honest,direct,solid,became the antonym of hip or hep or sphisticated,at least in the U.S.A.Someone who didn't like or pretend to understand jazz and swing was "square." The word came to have a somewhat broadened use as out of touch,conventional,old-fashioned,not "with it." The latter expression is as dated as "Be there or be square."

e there or be squre 是很久以前美国人约会对方最后说的一句话,Squre 这里可以理解为卷铺盖走人.当然是句玩笑话,“要不你就赴约,要不就就卷铺盖走人”翻译成中文当然是“不见不散”
这是很过时的英语了,现在大家会说“Don't miss it"
