There's a lot of tags out there that describe multiple characters preforming the same action together or having the same thing happen to them. These tags are still useful separate from the group and large_group tags. Searching group transformation gets lots of results of people transforming in the middle of crowds or with friends that are not transforming, while group_transformation only gets multiple people being transformed.

The problem is that there are tons of them with no standardization. Many of them also have an underdeveloped wiki or no wiki entry. Almost all of them still need implications. As it is, it is hard to find these tags or know if you're using the right one, which is likely a part of why they are so under tagged.

I believe that the best way to handle these tags would be to alias and merge them to mirror the general group and large_group tags. Under this system, each subject that needs these tags would have group_verb tag that refers to 3 or more characters effected and a mass_verb tag to refer to 10+ characters effected. A duo_verb tag may also be used for some subjects. While I don't think it is as useful, several subjects have a multiple_verb tags that refer to 2+ characters effected. These should be grandfathered in.
No "trio_verb" tags should be used because they are more specific than the general character count tags. "solo_verb" tags should not be used because their effect can be created by combining solo or solo_focus and any tag.
There are still edge cases where this won't work. This is a large project I'm not familiar with some of these tags, so I'd like to discuss and ask for opinions here.

I have done the best I can to locate all of these tags. Here are my findings.

*multiple_pregnancies - applies at 3+ oddly

This is because of the equally odd both_pregnant tag. :/

multiple_pregnancies and both_pregnant should probably alias to the group_pregnancy tag.

For bondage there's the cobondage and bound_together tags, but those might be too specific for this. They could imply group_bondage.

Thanks for pointing it out, I'll add it to the list.

I would alias both_pregnant to duo_pregnant, alias group_pregnancy to group_pregnant, bulk update multiple_pregnancies to group_pregnant, then have all that remain with tags in them imply multiple_pregnant. This way all of them would end in pregnant, and group_pregnant would match the general group tag's definition. Lobbing all the tags together into one isn't the goal, having different tags for different amounts is still valuable.

cobondage wiki:

Not to be confused with

• bound_together - Tag this instead if the post has no fetishist/sexual tones.

Weird definition. I don't think it's possible to have non fetishy bondage, and that is certainly not how bound_together is being used.

More possibly related tags:

• Parallel_sex - Two or more sets of characters are performing sex acts independent of yet beside each other.
• Mutual_chastity - used to describe a dynamic where both/several characters are in chastity, as opposed to the typical key holder (dom) + character in chastity (sub) relationship. Or perhaps a more straightforward definition would be "when there are multiple characters in chastity together"? Currently lacks a wiki.
• Hands_everywhere - many characters or disembodied hands groping/teasing/etc. the same character. (Minimum of 5 hand, according to the wiki)

Mutual_chastity is an interesting one. Right now it seems to be used for any image with 2+ characters in chastity, but if we have it imply multiple_chastity, another way it could be used is for images where the dom is in chastity as well as their sub while excluding images where there are only several subs in chastity.

Duo transformation can be depicted with more than 2 characters present; the rest can just not be transforming. post #3681830

Fixed it. Can't believe I missed that.

I think trio transformation should imply group transformation instead of being aliased away. We have trio and trio_focus both imply group, so why can't trio transformations? Plus, it can be helpful for those who want to find exactly three characters transforming in an image or find four or more transformations happening at once overwhelming or just too much.

I was against it because less tags makes things more easy to learn, and an image with 3 characters is not as starkly different from an image with 4 characters the same way 2 and 3 are, but I do see your point. We're missing a middle size because 3-9 characters in an image has a very different feel at different ends of the scale. I'll keep trio and give it implications if anyone else is in favor of it. I'll also argue in favor of a 5+ instead of or in addition to the trio tag, since it'd have parity with orgy which already uses 5 as it's cut off, and 4 is the maximum for human subitizing or counting at a glance. Not sure what to call it though because medium_group doesn't sound right.
