When someone is so ugly that it becomes what they're known for (i.e. their trademark)
Guy1: Who the frig is Jenny*? she's trying to add me on facebook.
Guy2: I think she went to high school with us but, i don't fully remeber her...i just remember her trademark was her ugliness
Guy1: Oh yeah...she was trademark ugly, wasn't she.
