|1.||girlfriend without benefits|
An extremely close female friend whom you treat like a girlfriend (hugging, jokingly hitting on each other, hanging out all the time), but, for whatever reason, you never get physical.
1: So you two are dating, right?
2: Haha! No, I can see why you'd think that, but she's more like my girlfriend without benefits.
1: Wait, I thought you guys were going out!
2: Oh hells no, I'm (dating someone else/not into him like that/actually gay/whatever). I'm just his girlfriend without benefits.
