S1·E13 Slumber Party

Brenda invites Kelly, Donna and Andrea over for a "night of female bonding." They are having a good time until Kelly's friend Amanda shows up. She insults everyone and decides to turn the girls against each other. As part of a "game" about secrets, Amanda bullies Kelly into describing her first sexual encounter, in which she was humiliated by the football captain. After Brenda recalls stealing a Minnesota friend's boyfriend, Kelly admits that she tried to hit on Dylan. The girls eventually make up, and Brenda and Kelly vow to never let a man come between them. Amanda's behavior is attributed to a diet pill addiction. The girls catch David and Scott lurking outside the window and taking pictures of them. Brandon and Steve are denied entry to a club, but hook up with two girls. They steal Steve's Corvette, but he doesn't press charges (and pays their traffic ticket) because he foolishly thinks that he and Brandon still have a chance with them.
