如果形容某人是 hanging around，意思就是此人无所事事，没有目的地闲逛。
- I like going shopping with my friends but we spend most of the day just hanging around in the mall.
- I don‘t think he really loves me. I‘m getting sick of hanging around waiting for him to call.
- There is nothing for teenagers to do round here. They just spend their evenings hanging around street corners.
值得注意的是，to gang up on someone 的意思是在通话过程中由于某种原因突然把电话挂断。
- If you don‘t stop shouting at me, I‘m hanging up right now!
