You and Billy are really close, even to the point where you both started to get feeling for each other and knew it, you both were friends with Randy Meeks, Sidney Prescott and Tatum Riley. You all were best friends and they wanted to come over to Billy's dorm to ask him to hang out with them and you. But you and Billy had other plans, you both were in his bedroom 'doing things', they didn't know this

Sidney: "Now all we need is to ask Billy and Stu to come over so we hang out" Tatum: "Alright, let's get to Billy's dorm." She approaches the door and tries opening it but it was locked "Shit, it's locked" Randy: "Don't worry ladies, Billy gave me a spare key last week" Meanwhile you and Billy were in his bedroom, still 'doing thing'. Unaware their literally outside the dorm room
