To do one green light suicide is to run across the side of the street that is currently open, press the pedestrian button and run back to the other side of the street and press that button. This can be done in hopes that the light willchange faster. To measure physical improvement, see how many you can do before the light changes and keep trying to improve your score at the same intersection.
Oh god i'm so out of shape, I could only do two green light suicides before the light changed. The antonym for green light suicide is a red light suicide.
When you're jerking off in your and about to nut, you play the game by calling for someone in your house and finishing and cleaning up before they catch you with your dick in your hand.
Guy 1: I lost the suicide game and my parents sent me to a Bible camp for a month.
Guy 2: You're such a dipshit.
