Also known as "Squestion Game," it's a question-and-answer game where the people take turn asking each other questions. Commonly used over the internet in Erotic Roleplay (more commonly known as ERP or Cyber), it can be used in actual sex.
Nel and Zox had an awkward moment of silence in their ERP.
Zox: Wanna play Squestions?
Zox: Are you jacking it right now?
