美国俚语经常打招呼的意思？

what is your man 应该是：what is my man。这个是 How is my man doing? / How is my man doing today? 的错误语法的说法。my man是黑人常用的称呼朋友的口语，意思是：my friend, my brother。

yo wassup = Yo! (=喂/哎）What's up?
howzit = How is it? (=今天/最近如何？)

How is it going？通常说为： How's going?

另外常说的打招呼话还有：
Hi!
Hey!
Hey, dude!
Hello!
How are you?
What are you up to?
What you up to?
Hey hey hey! Look who's here?
Yo!
Yo man!
Dude!
My man!
Hey Man!
What's up?
What's up, dude?
How's going?
How's going, dude?
How's it?
Monring! (= Good morning!)
Hey, big guy! (称呼比你高大的）
Hey, little guy! (称呼比你小的，或昵称小男孩）
Hey girl!
Hey brother!
Yo brother!

yo wassup
howzit
上述两个说法比较普通，从西海岸的黑人街区开始的，如今都这么说。也没什么意思，就是打个招呼。
至于你说的what is your man， 美国没有的说法。

估计你说的 what is your man 是 what's up， man?
可以翻译成 “最近咋样， 兄弟？”
