Her initial motivation was $400. I don't know what went on after that but she didn't show up because she likes to party with frat boys. Money was always the objective.
My working theory is that she heard some racial comments and initially stopped dancing and left because of it. Did she go back and stage a rape to get back at the folks who said crude things to her or was she actually assaulted? I'm still open to either possibility being true.
If she did plan to stage a rape, I'm not sure why she'd feel it was prudent to leave her purse and her cell behind. Either one could give up compromising information about her. If she was already messed up, maybe that explains her poor thinking but it might also make her less likely to come up with such a plan to start with. That's where I really have trouble connecting the dots of the students' story.
Her initial motivation was $400 plus tips.
Reliable source tell me that strippers who work parties usually make far more then the showup fee in tips. (I'm talking about strippers, hookers would make even more.) Something cut the show short. Being asked to do sick things with a broom stick might have made her not want the tip money badly enough to stay. The guys would have want'ed something for their $400. Racial slurs could well have been used, stuff could have been left behind. That could easily have pissed both strippers off to the point they decide to fix whitey.
