Gallaeci
A bunch of grumpy Celts who took over parts of Spain and Portugal. They spoke in a language that sounded like a sailor's curse.
My history class said the Gallaeci were like the original grumpy old men of the ancient world.
My brother claims the Gallaeci were just a bunch of sailors who never left the boat.
I think the Gallaeci were just a bunch of angry people who hated everyone.
