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: βWhy canβt we talk to other kinds of people?β
Heather Chandler: βFuck me gently with a chainsaw. Do I look like Mother Theresa?β
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!"
Fuck me boots, are just that. The art of having sex with a pair of women's boots. Full length zippered boots work best as cum catchers (as my old girl friend used to call them)In zip boot place in vinyl or leather side into and around whole crotch area with the shoe part of the boot sticking up out of your underpants and lay on a pillow and enjoy your wife, girl friends, sisters, mothers, etc boots) You may also place the second boot on a pillow at your face for kissing and licking.
'Image not really into it tonight after an exhausting day. Why don't you just use a pair of my 'fuck me boots' and enjoy them. Just make sure you clean them up good after your done with them'
