For Danbooru purposes, this tag refers to images where the breasts are noticeable, i.e. you should not use this tag to describe a flat-chested girl.
If unsure of the breast size, this tag can be used by itself as a catch-all tag, i.e. without the size modifier.
Note: It should be noted that exposed breasts alone usually don't warrant an "explicit" rating.
