Your Sex Song. The song that was on when you first had sex with your partner. It usually changes from couple to couple, and upon getting a new partner, a new one is set. NEVER use the same SeSon with another person. One relationship to one SeSon.
Elizabeth: So, what's your SeSon at the moment?
Emily: It's LoveGame.
Elizabeth: Oh my god! Mine too!
