look up any word, like basic bitch:
The term to describe the movement of an old person's hair line from the original position that it was at during their youth, but has moved back to the base of their head.
Candy: Mr. Smith's an old man.

Hannah: What makes you say that, Candy?

Candy: Have you seen his hair line? It's so migratious.
