On Danbooru, that tag is called "headboob".

Personally, I prefer the term "milkbagging".

You didn't have to remove breast_rest though.

I did it to cut down on the tag clutter. Since headboob is basically a subcategory of breast_rest, there's no point in having both tags on one picture.

Nice turn of phrase.

As long as it's consistent, I have no objections.
