create alias twin_tail (0) -> twintails_(disambiguation) (0)
create alias double_tail (10) -> 2_tails (9873)
create alias twintail (0) -> twintails_(disambiguation) (0)

Reason: These 2 tags are both redundant and confused, they are used to refer to either 2_tails, pigtails (twin_ponytails) and forked_tail. Which is why I propose forcing an alias on them to make them disappear entirely.

I propose twin_tail should lead to a disambiguation for the aforementioned 2_tails, pigtails and forked_tail, as I find the term too ambiguous between the 3.
Meanwhile, I went through double_tail tagged posts to remove the few non-2_tails instances for a clean aliasing, as I find the term less ambiguous.

There also existed a twin_tailed tag with only 6 posts that I simply wiped clean. As I assume the newly created twin_tail_(disambiguation) tag will clue in future users and point them towards the tag they are looking for.

EDIT:
I've noticed the existence of the twintails_(disambiguation) tag that is pretty much EXACTLY the same thing my BUR request, but for the plurals twin_tails and twintails, dating 2015.
Seeing that, I edited my BUR to point directly to this old tag instead, no point having two of them.

Taking cues from the 2015 disambiguation, I added an alias for twintail to lead to the disambiguation. It's currently unused, but I'm taking the initiative to prevent future workaround attempts.
Workarounds such as the twintails_(hairstyle) tag I just spotted. It has over 1k uses and both my BUR and the 2015 disambiguation would agree it should be aliased to pigtails.

Hmm, two examples. Made sure both had mult_tail for those characters. I guess the others might need to be done, as well? Bah, I'm being dumb. I should have added 2_tails since it implicates multi_tail. :(

https://e621.net/posts?tags=twin_tail+-2_tails I found it less annoying if I reduced it first by doing single characters at a time. ;)

https://e621.net/posts/4002727?q=twin_tail+-2_tails This is the hairstyle, so yeah, this is why it's a disambiguation.

Do keep in mind that Espeon's tail is a forked tail, not 2 tails/multi tail (even if some few art pieces take the liberty to make it 2 tails instead).

I made this BUR in part because I once used twin tail instead of forked tail to describe Espeon's two-tipped tail, because I didn't know the right term for it.

Ah, right, I'd better double-check that. Only the first result was forked_tail. Rest were multiple tails.
https://e621.net/posts?tags=double_tail+-2_tails Probably a few of those are forked tails? Oh right, "Meanwhile, I went through double_tail tagged posts to remove the few non-2_tails instances for a clean aliasing, as I find the term less ambiguous." so I guess you already dealt with it.

https://e621.net/posts?tags=twin_tail+-2_tails+-forked_tail+-pigtails I have no idea on those videos. I'm sure once it's pointed out, I won't be able to unsee which it is.

From what I'm seeing, the tag in those is meant for the redhair's pigtails.

OK, just wasn't sure as it's really hard to see. I thought there was only ponytails.

For that last one, topic #30951 has a discussion on how twintails and pigtails could be differentiated.
But as current e6 tagging rules stand, as defined by twintails_(disambiguation), they are one and the same.

I added a link to these two topics there. You could add specific details from these posts to the Wiki article. Hmm, some examples of each in the article itself might be handy.

There's a nice feature that lets you add more complex search results to a post. Use curly braces like this: \{\{tag1 tag2 -tag3 -wildcard*\}\}
pigtails rating:safe -twin_braids gives you safe examples like one I pulled from last page of results, to put into the Wiki article.

Ugh, messed up the escape codes but you can see which I used.

TBH, if there's workarounds happening, it might be telling us something. :/

I kind of agree, when you say "pigtails" most people would specifically picture somewhat short double ponytails like Muffet has. While the more common Hatsune Miku-esque longer ponytails come to mind as "twintails".

IMO I think the issue would be partly negated if twintails was the default name instead of pigtails.
Twintails feels more general/neutral than pigtails for "hair attached in 2 different strands" and would be a better fit (albeit not perfect) for the miscellaneous hairstyles that are lumped into the current pigtails tag.

A more general umbrella "attached hair" tag (with ponytail, twintails/pigtails, hair bun[...] implying it) could also alleviate some ambiguous tagging and various edge cases.

But this is a subject for another forum topic. Just in case, I'll keep twintails_(hairstyle) out of my BUR and leave that decision for alias #54540.
