Nametag?
If you’ve ever been told by a parent or authority figure that they were going to tattoo something across your forehead, then this guy has taken that warning to heart. He’s decided to beat someone else to the punch and tattooed himself first!
The downside is that instead of choosing something positive, he went with something that might be accurate but comes across as negative. He can hide it by growing out his bangs, but he will know it’s there.
