Aliasing slut → nymphomaniac
Link to alias

Reason:

Quote from slut wiki:

General: slut

A slut, also known as a "sex addict" or a "nymphomaniac",

IMO nymphomaniac is more precise and not derogatory term for this.

Nymphomania: Uncontrollable or excessive sexual desire in a woman. Compare with satyriasis.

Satyriasis: Uncontrollable or excessive sexual desire in a man. Compare with nymphomania.

-1. I would argue that nymphomania isn't really any less derogatory since it stems from women being promiscuous as being something that's "wrong". They now classify under "sexual disorder" or "hypersexuality" in the DSM-5 (and probably the ICD-10-CM, but I'm less familiar with the ICD) and avoid the terms entirely.

Though I'd prefer to get rid of slut tbh. There a lot of posts that wouldn't make sense to be tagged as either, and I don't think people would stop tagging "slut" unless it was invalidated and hand-replaced with a different term.

There are some posts that it works for:

post #219123 post #540387 post #537304 post #237486

But for these it seems to be tagged for no particular reason:

post #542851 post #515880 (arguably)

While posts like this would be better tagged with something like "cheating" (or whatever the correct tag is):

post #250584

And this would go better under prostitute:

post #213948

It definitely needs some cleaning up before it's aliased to anything at the very least.

+1 for aliasing both tags to invalid_tag.

I didn't know that nymphomania is gender related term. If that's the case then of course my suggestion is wrong.
I don't mind getting rid of slut tag.

Plus one for invalidating both. I've never liked the slut and slutty tags, it's too subjective and those get tagged for all kinds of images. In many cases, tagging seductive and skimpy would be more accurate.
