When someone is called a 5head, they're usually really smart. The idea is that big foreheads = more brain = bigger smart.

person 1: *solves something

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

The word forehead doesn't describe the size of the forehead enough, thus the word: "5head"

1: "Wow he's got such a big forehead. Who is that?"
2: "Oh him? That's Twitch streamer Juice, that's not a forehead, that's a 5head"
1: "damn"
