I don't think it was discussed on the podcast or earlier in the message boards, but there is another incredibly ridiculous line. They are meeting another woman at the restaurant shortly after they shot that guy in the face.
Donna says "I just shot Seth Romero in the face. I should've killed him."
The girl they're meeting responds with "You may wish you had. The best you can hope for now is crutches."
Crutches? For being shot in the face? Hahahaha. I had to rewind it to make sure I heard correctly. I know its nothing compared to all the sexist and genuinely awful moments of dialogue in this movie but I thought it should at least be brought up.
