The exact opposite of friends with benefit. It's like having a girlfriend but with all the bad parts and none of the good parts. You go through all the boyfriend/girlfriend drama and there's no making out, no hugging, holding hands, NONE of the good stuff. The worst possible relationship you can have with a girl, worse than being in the friend zone.
Jon: Yo, where's Michael at?
Alex: He's back there with his not-girlfriend, they're arguing about something.
Jon: Offff course they are.

Get the not-girlfriendmug. A girl that you care about very much and she cares about you too but for some reason, past experiences etc. She is too terrified to commit to being your "Girlfriend". You are exclusive, you do most of the things you would do with a "Girlfriend" just don't sport the title yet.
Who was that beautiful girl you were with at the movies last night? That was Nat, she's my "not-Girlfriend".
