The Batman Game

The act of dressing in a leather S&M gear and masturbating using auto-erotic asphyxiation. One who partakes is called the Batman, but any bystander or partner is the Robin.

Zach: Did you hear about bobby?
Ted: No what happened?
Zach: He died playing the batman game last night with Luke. He suffocated, it's pretty sad.
Ted: Damn, I still can't believe Luke Robin-ed him too.
