Not the parent, but I assume they mean the nose stud, green or blue hair that looks like it's needed to be redone for a month (but was, in fact, dyed yesterday), and at least one full-sleeve tattoo, look.

[EDIT] For the record, I've seen women with that look who weren't very good, and I've seen plenty who looked different from that who were good. I don't agree with their broader assessment.
