chesticles
balls as breasts
testicle breasts
breast balls

recently had the second tag brought to my attention while trying to respond to a tag-related query on the Discord. after further searching and looking at further posts it occurs to me that these tag names suck balls

without looking at the wikis, i want you to guess what each tag means.
* balls being raised to the chest to give the appearance of false breasts
* same as the first one, lmaoooooooooooooooooooooooooo
* balls being directly attached to the chest like breasts are
* breasts being directly attached to the groin like balls are
how'd you score? probably 2/4 or lower, right?

so, while i'm perfectly fine with aliasing two of these tags together, i've already had to fix a mistag. i think the mere existence of these tags is going to introduce multiple problems if they catch on with the userbase. currently, they don't even make up 100 posts collectively, but i know there's at least one other image of a tanuki guy doing this (it might not currently be on e621?) there's every reason to believe that all of these tags are, well, undertagged.

TL;DR: we have a bunch of balls/breasts-related tags (breasts between legs, testicles on chest, testicles being pushed way up to chest region) with names that are too similar to each other, how do we make them more distinct?

Oh yeah the balls as breasts and chesticles similarity were brought up recently in topic #45597, though the other two are new to me.

One way to make them more distinct is to give them implications to unusual_*_placement, and rename them to something like *_in_place_of_* for the other two.
