This happened to me on Saturday night! I was gaming a girl asked her to pick a number between one and four and she says
HB "You're doing the game!".
Bloke "What are you talking about?"
HB "The Game! I know you're doing it"
Bloke "Yeah my brothers a psychologist he taught me this game"
HB" " I know how it works"
Bloke "Okay GO are you thinking of 2??"
HB "No it's 3"
Bloke "Oh my brother told me it's always 2

"
The key is to have a very strong frame. Make her feel silly for saying something so random and foreign to your innocent ears. Eventually I isolated her and she told me
HB "The Game is a Secret Society of guys who get chicks."
Bloke "Like the Illuminate?"
I told her a story about how I tried to join the Illuminate and mum cracked it. Then she explained more about "The Game" to me I acted interested and dumb the whole time.
So a girl ended up telling me how the game works (to the best of her ability). She told me she'd blown off other guys in the past she'd caught using the game on her (bloke "Wait! You actually met guys from this secret society??".) Yet I went on a day 2 with her yesterday and it's pretty much a done deal. On the date she tells me even more about the game, amazing.
It comes down to 2 things if you get busted gaming
1. A strong frame
2. Confidence in the fact that if your game is strong a girl probably won't know half as much as you do. It's likely she'll know what a neg and a cube is and that's it.
(for the record I ran the cube on her too, another one of my brothers psychological tests lol!)
