Some people consider hey to be an inappropriate greeting (hay is for horses), but among those who do not, i wouldn't say that hey yourself has any inherently negative connotation. It seems like the correct spelling is “but, hey,” however, especially when followed by a clause, the pauses (perhaps) become excessive and the comma is frequently dropped. 天天在我耳边说 man, man, what can i say,问他是什么意思又不说。
It can be used as either a pithy bon mot to jostle a friend, or a snide comment to completely distract and put off a mere. 'hey' ( perhaps originally a natural expression) appears to be at the origin of 'hi', while 'hello' seems to have no connection with the previous two terms and a different origin. 邓紫棋在点评 《hey kong》 的时候,有句话正片里被剪掉了,《新说唱官方bot》中可以看到,大概在34分钟左右,大意是说聪哥不用一直这么刚硬,其实你是个很善良温暖的人。 邓紫棋说.
