also Argentinian. Guillermos are mysterious and serious, but there's a great sense of humor hidden under those hot latin looks. Can be a little bit of a slacker, but don't let the procrastination fool you, Guillermos are highly intelligent. Also have a sweet and genuine and lovable side- theres not many who can say they don't like a Guillermo. Generally not badass.
"Che, Guillermo. Que tal?"
"Tal tal. Y vos?"
