Any 3+ inch heel other than those appropriate for work. 
Do fuck me slippers exist?
Yes, but they only work in conjunction with a “trailer park moo moo”, a Natural Light beer in a John Deere cozy in one hand and a Slim 100 in the other (and dentures out if you really want to send “that signal”).
I’ve never heard of CFMPs, but I’ve heard of fuck me boots. This came from National Lampoon back in the 80s. They had a little blurb on how to tell the difference between a hooker and a highway patrol cop. A hooker wears fuck me boots. A highway patrol cop wears fuck you boots.
A word to the wise. CFMPs are NOT to be confused with sheep shankers.
Can I just point out that this term confused the hell out of me for ages- you see, in the UK, pumps look a little different… 
Guy here, and generally I’d characterise them as the kind of shoe worn by vintage cheeseckae pin-ups, as done by e.g. Gil Elvgren possibly NSFW Google Image Search and the like.
The magical power of a good pair of "CFM pumps"goes without saying . And puts off a very clear it deliberate message from any female… I would say a minimum 4 inch Spike heel is necessary… As an ex-girlfriend used to call them “sandals with handles”… And personally what’s work for me the best in the past is a minimum of 4 inches in order to get both heels in one hand and two pin her legs back…
Even an unprofessional environment instead of high heels you can give me a hard time at any time if you know what I mean
Something strong and long enough to grip and use as a handle ---------- or at least strong and long enough to plunge into a brain in the event of a zombie apocalypse.
Now if they only come in my size.
