I actually never saw the movie but I remember the trailer.
There were two teenage girls that escaped from a psychiatric hospital (pretty sure but it might have been a prison). I think they escape into a large city. I have this one quote recorded (just audio) from a long time ago.
Girl 1: “Do you think we’re psycho or are we normal?”
Girl 2: “Well we’re definitely not normal because normal sucks.”
There may have been a gun in the trailer.
