The bulk update request #11105 is pending approval.

remove alias chubby (0) -> slightly_chubby (159617)

Reason: The current alias leads to constant mistagging of slightly_chubby. 'Chubby' was (rightfully) aliased away as it isn't a technical term with a solid definition. It's a cutesy word that's fun to say, so people use it as a descriptor for all levels of fatness.
I don't think you'll be able to change that any more than you'll get babyfurs to drop 'crinkle' or ferals to stop using 'cookie.' What can be changed is removing the problematic alias.

Follow-up will either be moving chubby to a disambiguation or just changing its category to invalid.

There's a part of me that just wants the alias reversed since it's tedious to add "slightly_" to every instance and it's nicer to just say chubby like a normal person lol
But people are why we can't have nice things :P

I wanted to alias chubby to overweight, since I regularly find posts tagged slightly_chubby that are clearly more than slightly chubby, likely from people tagging chubby for overweight characters and it getting changed to slightly_chubby instead of the more correct overweight.

I don't know about a disambiguation or just moving it to invalid, but something should be done with this alias to cut down on mistags.

It's a pain because, both on e6 and just out in the world, I've seen it used for everything from 'stomach isn't flat/concave' to 'a baby/childlike body' to 'big cheeks' to 'big thighs' to 'hyper fat.'

It's an emotionally charged tag ever since (at least) the plus sized model phenomena

I've always thought it's baffling to have a slightly_chubby tag without a plain chubby tag, so in favor of this if only to stop making my brain itch.

IMO, a plain "chubby" tag is too vague next to overweight and slightly_chubby. There isn't much room in between to fit another distinct belly size tag. People will have too much variation and cause a lot of overlap with both, so leaving chubby as a valid tag isn't a good idea.
