What do guys mean when they say we should hang out sometime?

So me and this guy haven't talked for a while and when we were talking he was always sending mixed signals. So he hit me up recently and asked what I I've been up to, and then said that we should hang out sometime. I told him sure and to tell me when he wanted to hang. He has not replied so I don't know what his intent is on.
