A character talks about her mother, who had mental issues, which prompts another character to say some deeply disrespectful and hurtful things (on more occasions), using the word "crazy".
No, but I want to mention that a young woman snaps a picture of another young woman who's wearing no clothes (she's covering herself with part of the shower curtain and a towel) and says she'll share the picture on Snapchat.
A man is lying on the ground with a bucket on his head, a car drives over the bucket, which flattens, blood spraying from it. There's also a decapitation and two instances of someone having their head fully impaled.
A head is crushed, a head and a hand are severed, and a person is sliced in half, so technically yes. But I don't think there are any instances of what you'd normally call "breaking a bone".
