Because the movie is a comedic horror film, the violence is intentionally over the top, fake looking, and played for laughs.
Extreme graphic violence and gore throughout, including decapitations, disembowelings, and bisections via an oversized meat cleaver. Please note that the gore is wayyyy over the top (and somewhat intended to be comical).
A man slaughters an entire house : he chops ones face to ribbons, chops a man's head in half vertically, decapitates two, slashes one's back, stomps one one's head, chops at a woman's stomach which causes her intestines to gush out, chops a man from his crotch up (we see blood splatter) and breaks one's neck.
We see a woman with her feet cut off.
A man has a circular saw taken to his stomach and he then is decapitated.
A man has part of his face chopped at, his feet cut off and his arms cut off. A man is chopped in half horizontally.
In a flashback we see a man who has his head impaled on a stick.
We see a woman with half her face skinned off.
We see two people slaughter a group of teens : One has is legs cut off and is disemboweled, one has the eye bitten out, one is chopped in half horizontally, one' s head is smashed with a sledge, one is chopped at, the killers start hacking the corpses to pieces (we later see the dismembered parts).
A man has his throat slit.
A man has half has head chopped off.
A woman is bludgeoned by a car.
A clown is shot to death. Moments later we see the body. No blood or gore is involved.
At the end of the movie we see a woman driving a car covered in blood.
