5head
When people fit more than 4 fingers on their forehead, it is no longer called a forehead anymore. It is called a 5head or "fivehead" when they fit all 5 fingers or more on their forehead.
Guy 1: DAMN! that girl's 5head is like BIG, LIKE a HUMMER WINDSHIELD!

Guy 1: What does zoe and rihanna have in common?
Guy 2: What?
Guy 1: 5Heads

Girl 1: I have a forehead
Girl 2: I have a 5head...
Girl 1: If I had a 5head, I'd go fuck a dead goat and then suicide...
Girl 2: I'm going to do that right now...

Girl: Whenever I facepalm myself, it fails because my hand covers my 5head but now my face
