Comes from the mexican "Fuaaa Philosphy". The extra power you need to do something. The character and strength that projects to the universe and gives the extra power you need.
You´re tired? Fuaaa!
You´re sad? Fuaaa!
You´re sick? Fuaaa!
Someone´s dead and you want to revive him? Fuaaa!
No more ugly moments... Live by the Fuaaa Philosophy.
I´m soooo tired and I have a lot of work... Fuaaaa!!!
