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.

I went ice fishing and obtained giant frozen head over the weekend.

A giant made out of rocks with a big head that writes songs.

You got yourself stuck in a situation, you can get yourself out just as easily, just as easily because you got yourself stuck in a situation you can get yourself out just as easily just as easily
