One of the funniest dudes out there, usually not single but always knows how to get onto a ladies good side. Incredibly good with his words and alwayys knows what to say. Usually latino and always had Amazing hair. Can hold a grudge for eternity and has dumb comebacks that are so stupid its funny. Almost always an incredibly huge slacker but dont let it fool you, Guillermos are highly intelligent and are at first very quiet, but once befriended very talkative.

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.
