A girl whose head is so large it resembles a large melon. Often accompanied by grotesque facial features such as an oversized and misshapen chin, forehead and nose. To compensate for this serious lack of physical attractiveness, these people will often post unflattering nude pictures of themselves online for attention. Good luck with that.
You know that girl, Giant Mellen Head? What a troll.
