The STD game is where you engage in sexual intercourse with a newly-acquainted female. When you have almost reached your climax, you tell the woman that you have some kind of sexually transmitted disease/infection. The aim of the game is, once she tries repelling you, you try to ejaculate before she scurries away.
-I have chlamydia.
-GET THE FUCK OFF ME!!!
-Hahahahahah take it all bitch!"
"Yeah that's right, I played the STD game, what of it?"
