Nowadays movies and series portray the hook up culture in a normalised manner which is completely not true in real life.
It is a way of the system teaching and brainwashing men to have sex with random girls without knowing them.
It is better to stay away because you never know when a girl is going to file you against sexual assault or harassment.
She could even say that you raped her while she was drunk if she regrets the sex she had with you so just beware.
