I think she perfectly highlights how Josh just sees women as fuck holes.
She is like him in so many ways, Disgusting, no self-awareness, selfish, greedy, lazy, delusional, and the list just goes on and on… He was all for fucking the troglodyte, even beating his little peen to her saggy grapefruit tits. The second he saw this crazy bitch required some effort to get into her axe wound, he wanted nothing to do with her (actually right decision) but for a retard like him she is pretty much the best he will do.
I think he just sees women as a physical release and oddly, an indicator that he is ‘norma’l because he has a girlfriend.
