Commonly confused with literally fucking someone with a chainsaw. "Chainsaw Fuck" refers to any zombified like humans that chase you down with a chainsaw. They usually wear a potato sack over their head with one eye hole, and are most notably found in the Resident Evil 5 video game. Its weakness tends to be a shotgun blow to the abdomen and/or head at point blank range or a few magnum shots to the head region.
Popularized by the movie, "The Heathers", this phrase is said in response to a request one deems impossible or absurd (much like being gently fucked with a chainsaw). It's basically a way of showing someone how ridiculous what they've just asked sounds.
Ex.
Veronica: “Why can’t we talk to other kinds of people?”
Heather Chandler: “Fuck me gently with a chainsaw. Do I look like Mother Theresa?”
Dylan: "Hey Nick can I borrow your car once its out of the shop?"
"Fuck me gently with a chainsaw. You crashed it just last week!"
