I don't normally drop a hard W, but I think going to a frat party trawling for dicks that are old enough to be your kids' to fill all your holes makes it warranted. Now, I don't think she's actually going to do that, I'm just continuing the narrative.
I also just think it would be funny if she got more upset at "old" than "whore." I remember her saying she slapped a guy for calling her "black" during sex, so I could see it happening.
