a hispanic person, usually a puerto rican or dominican, who represent their culture every minute of their life. they speak spanish all they time or most of the time and when they speak english it turns out being spanglish. they always listen to reggaeton and when they're in the car they find the need to blast their music so you can hear it when you like a block away, so all you hear is the reggaeton beat. and about 6 out of 7 days of the week they're usually wearing some piece of clothing that has a picture of their flag or something about their nationality.
but ya gotta love 'em
