This movie is a dark comedy with plenty of violence and murders. The violence, although usually played for laughs, is very brutal and bloody, and involves a few disturbing, tasteless, and/or gorey scenes.
A woman is killed when her head accidentally slams onto a coat hook (we see the large bloody wound in the back of her head, more than once). For an extended period, we see her dead body lying on the floor in a pool of blood.
A man is stabbed in the chest several times with a corkscrew; then some men hold the bathroom's door shut, keeping him closed inside the room while waiting for him to die (we hear him screaming and begging for help as he gasps and dies). Afterwards they enter the room, which has blood smeared literally everywhere: walls, floor, bathtub (we see this for an extended time).
A man dismembers two dead bodies with an electric saw (we see a piece of bloody flesh on the saw, as well as the dead man's body moving as he cuts).
Several bloody severed limbs are being wrapped in plastic and loaded into suitcases, then buried in the desert.
A woman repeatedly smashes a man's head until he is unconscious and extremely bloody (only one hitting is onscreen, the others are offscreen). Afterwards he is seen covered in blood for a long time, until a man opens a door, accidentally hitting him, who was behind it; then he falls down the stairs, breaks his neck to a wall, and dies.
A man drives his car into another vehicle and crushes a man (the impact is really violent). Later we see the victim in the hospital covered in bloody wounds and bandages; he dies.
A man tries to suffocate a woman with a pillow. She reacts, hits him in the head, then bites his crotch area hard (he is fully clothed and screams loudly). They struggle and fight, then fall through a glass window, violently breaking it. We later learn that she was killed by the man (nothing is seen).
We hear a gunshot, then hear that a man was killed (completely offscreen).
A truck crashes into a car with two men and a dog in it; a man is thrown through the windshield. We later see that one of the passengers had both his legs amputated, the other man is a vegetable confined to a wheelchair, and the dog has lost a leg.
A man prepares to kill another man with a shovel, but does not do it.
Several brawls and arguments.
