Apparently words like "dating" and "hanging out" aren't good enough to describe that phase between hooking up and being in an exclusive relationship . . . someone just HAD to go and make up a new word for it.
That's what people do in 2017.And the word is . . . "situationship."
That's the new term for two people who aren't quite in a relationship, but are definitely involved in SOMETHING. Now you know.
