aguerrido
It's a mexican person, that think they're all that. They are ugly and have no life, they will have a hard time in life. They are bums that like to start problems and run their mouths, but they're stupid so they don't know better. Never be close to someone having the last name: Aguerrido. They are lame and low lifes.
Aguerrido people are 100% retarded
