[NSFW] "Impossibly Large Breasts"

I understand if it’s like BadgerBen’s art where the breasts are twice the size of the entire body, but there are a lot of images tagged under it that actually are just larger-than-normal breasts.
 
If this can exist irl~  
 
then it’s not “impossibly large”

Also, there are breasts even larger than that, although when it gets to that point, it’s a disease

^ This is one of many tagged ‘impossibly large’

It’s one of those examples where it’s absolutely impossible to draw a clear line between “large” and “impossibly large”. It will always be subjective.

I understand what you mean nd yes, in some cases it is horribly mistagged, but that’s the official problem here, subjectivity messing up with people.
 
the same sort of thing can and does happen to impossibly large derrieres.

This is only a suggestion, but a way to give at least some guidance on where to draw the line might be:  
Breasts exaggerated to the point that they aren’t just abnormally large, they also look out of place on the body. In other words, something like >>1281569 would not be, since the character is so curvy, but that same breast size might qualify for the tag on an image like >>1204625 because of the mismatch. An exception could be made for cases where everything is exaggerated, but it would still have to qualify as looking “out of place” (that is, the body type itself is outside the realm of possibility).
 
I realize this is in no way less subjective, but it does at least give some framework for judging cases where the breasts take up less than 40% of the body mass. What do you think?

I’ve said the same thing before, many times. Like others said, the problem is subjectivity. The closest I ever got to a reasonable response was when I was pointing out Norma Stitz to someone and he was pointing out the girl in the picture may have had smaller breasts, but she was also much skinnier than Norma, so her tits would’ve been impossible for her frame.
 
Anecdote aside, it’s really not something we can fix without requiring artists to give measurements for all their characters or something (which I hope is obviously stupid.)
