What is the meaning of the word Guerto or Guerdo

[Buckland]

Hello, sorry for the question by I had a dream where I was flying and yelling the word Guerto or possibly Guerdo. It sounds Spanish to me. Does it mean something?

¡Hola!
Güero means "white boy/white man." It is used as an alternative for "rubio" in México.
