he said she said
An argument between a guy and a gal where the points made on either side can't be proven convincingly enough by either party to someone who has no clue what they're arguing about. Further exacerbated because you have no idea if either person is exaggerating or telling the truth and so nothing can be resolved. You know someone is lying about something, you just can't tell who. Usually the argument revolves around the relationship, money (who spends more on who), or some other pointless crap. Usually they've reached a point in their relationship where they really shouldn't be together and they're just arguing about anything and everything just to argue. Lawsuits can come from this.
Guy: "This b**** told me that she's never been with anybody before, but I found out she's been with a dude who died 3 years ago and didn't tell me about it!"
Gal: "That wasn't a romantic relationship! He was gay! I was just his friend!"
Third party: "Yeah, I can't tell if either of you is telling the truth. The dude's dead and so any proof of him being gay probably died with him if we was in the closet to everybody else. Gal, the gay card could be an excuse to get out of a lie. And you, guy, you could just be a jealous jackass and making this stuff up. It's a classic he said she said."
