ok a little more research shows that there are two main sites that mention "arithmophilia." Every other source seems to copy from one of them. Both are... pretty neat, actually, but are clearly just etymological wankery.

in fact, one outright admits these are purely hypothetical and were all cribbed from a list of phobias.

the other was written as clickbait for a "sex education" website

one truly is the loneliest number. harry nilsson, you were a genius. ;_;

@zebratron2084

So what kind of body numbering we talking about? Only mysterious natural Arabic numerals? How do you feel about bodies with registration numbers like a boat or a plane? Mysterious serial numbers? What about Roman numeral tattoos? Is it still good if the bodies are synthetic?

@001zlnv I mean, these are all very yes. If we were playing the Raggedy Ann and Andy Drinking Game[1], I'd have had to do five shots just now.

[1] "Watch a piece of media. If you see one of your kinks represented, drink. It DEFINITELY counts even if the instance on screen is unattractive or undesirable."

And presumably increment myself appropriately...

*sigh*

*drink*

Six.

@zebratron2084

so how do you feel about cyber limbs with part numbers and serial numbers stamped on each component?

@zebratron2084

oh and related to your love of skin numbering have you watched "cannon busters"?

@001zlnv I have not! Anime?

@zebratron2084

Yep. mild spoilers ahead

For reasons not yet explained the protagonist dies, and then regenerates. Each time it happens another number appears on his skin

@001zlnv you can imagine what infinity train did to me too

@zebratron2084

Totally

@zebratron2084 Somewhere I have a Fantastic Four comic book I got in Singapore in the 2000s where they battle an unstoppable (computer?) villain whose body is a whole great mass of mathematical symbols. I'll see if I can find and get some snaps to you.

Spoiler: Unstoppable Math Demon gets stopped, although in a way that's dumb in the way Silver Age stories are dumb, so I remember liking it that way.

@Austin_Dern Oh I would be very entertained by that! n.n

@zebratron2084 Found what turns out to be just part 1 of this; I know I have parts 2 and 3 somewhere. This is a Singaporean reprint so I don't know the 'real' circa 2002 books it was in.

Reed Richards invents a subspace-linked PDA and what do you know but it decides to attack Ben and Sue when they just want to see a movie.

ArithMonster (to call it something) can do the T-1000 recovery from being smashed ... and has a tender side!

@zebratron2084 ... Have to say, "liquid-morphing subspace monster made of calculus symbols and PDA energy out to destroy the world apart from the one creature it loves" seems like somebody was keysmashing on someone's Buttons.
