Used when someone is clearly making up an excuse for something. Derived from the kids who would always claim they had a girlfriend but that "you wouldn't know her, she goes to another school".
Jack: I'm usually good at throwing a frisbee, it must be the wind.
Elliot: Yeah dude totally, "she goes to another school".
Ray: "That's right - that's the way she goes. That's what I said - "
Bubbles: "So you lost all our drink money is what 'she goes' - she's gone."
Ray: "That's right - that's the way she goes. Sometimes she goes, sometimes it doesn't. She didn't go. That's the way she goes."
Bubbles, being interviewed moments later: "It was gonna be the best night ever, now it's the worst night ever. Fuckin' 'way she goes', he said, fuckin' way she goes..."
"in she goes" a term for a room/area/drawer where you storeeverything and anything. It's a common practice with people who hoard or have no organisational skills.
"Hey Steph, where would you like me to put this empty vase?"
Steph: oh just put that in the in she goes room. You'll find a spot.
The person then proceeds to the in she goes room and can barely open the door because there is that much shit in there you can't even see the floor.
