I'm trying to find out how to blacklist characters that are big/fat and/or muscled, I don't really know how to describe it, see some pictures:

Like they're fat characters but their fat is basically just muscles I guess? And I'm not sure how to go about blacklisting it.

If I look at muscular/biceps/abs tag it shows characters who aren't big so I would be blacklisting the wrong thing then, and outside those 2 tags I don't really see any other tag to describe such character design.

I do see one post has big belly/biceps/muscles tag but then many others do not so that still wouldn't help much. I think these characters are like ''bara'' design I think is what it's called? But It doesn't seem like there exists a tag for it.

barazoku exists, and you can also blacklist (or exempt) posts by using id:x metatags. Here's an unrelated line from my blacklist:
death -id:1205628 -id:1206064 -id:3813233 -fav:me

Unfortunately that only worked on the last image I posted, does that mean I should tag the other 4 images I posted with ''barazoku'' then? As at a glance they do seem to fit in with that tag as well.

Oh didn't know blacklist could be used that way, that will come in use.
