A sarcastic term used to describe an event or experience that was not really enjoyable to anyone and thus should be avoided in the future and usually a sign you may never see that person ever again. Similar to "it's been real" but more direct in definition.
I have to go now "it's been fun" I really enjoyed your party, but I really have to get going, maybe we can do it again sometime.
