The fact women going crazy over the shooter is just making dating harder. Now on a third date you’re absolutely getting asked “yeah but would you sacrifice your life and take out a high profile CEO for me or are you just looking for a situationship?”
That is at least a bit more specific than a fling.
It’s used pejoratively. On the surface it’s a relationship without labels. In practice one person catches feelings and their friends use this word to convince them to find someone who will actually commit to them.
