The spank ass game is where you go to a public place that has women of legal age like walmart or even the library. You look at the face and ass and if there sexy enough you walk behind them and pretend to bump into them but lightly smack there ass so they don't notice you and walk away. you see how many different asses you can smack with out getting caught by anyone! smacking the same ass doesn't count and they may get suspicious if you do!
