Based on Art Fight's nudity guide, which is by Anolee (click the spoiler button under "Visual Guide to Nudity Filters"). I fucking love the term "feral nipples" (i.e. belly nipples, "feral" in the sense of "not anthro"). They've been using the term "feral nipples" for at least a couple iterations of the nudity guide; the previous one by Spottedphyre says it too.
