We should hang out some time

A sentence used as a polite way to brush off someone you've been having a conversation with for more than two minutes. There's no intention of ever actually hanging out with the person. It's just an easier way of saying, "I have to go. Bye now."

A: You've really done a lot for this community.
B: Heh... I guess you can say that.
A: Without your efforts, we'd still be in crippling debt.
B: Mhm... Yep.
A: How were you able to pull all this off in such a short amount of time?
B: Hey, we should hang out some time.
A: Oh... Yeah! Sounds good! What days are you off this week?
B: See you around.
