Atle is the Norwegian form of Atli which is the Old Norse form of Attila which possibly means "little father" from Gothic atta "father" combined with a diminutive suffix.
He is a Viking from the North, known for loving cheese and milk. Usually white masculine guy with long hair, and many milk cartons in his fridge. If you ever need a man for the mission, stock up on milk and cheese, and he'll accept any day of the week!
Wow, this is a lot of milk, you having Atle over anytime soon?
Yeah, I have a score to settle...
