I heard this earlier today when I was talking with a co-worker. She said it's something her mom told her when she started dating. I don't know if it's something that has 1 specific meaning or if it can be interpreted in a way that fits "you" or "your life" or something.
"The player is always the playee. The playee always gets played. And the unsuspecting 3rd party.... they never wanted to be in the game in the 1st place.... be careful who you invite into your life.... or back into it. You could find yourself playing a game where no one wins - ever."
