A white girl of any ethnic background whether it be a white girl of Latin American origin or not.
Black and Brown Colombians often refer to white Colombian females as Blanquitas.
White girl. Analagous to latina
So I'm at the movies yesterday and you know how I like to put my things on the seat next to me? And this blanquita wants to put her things in the same seat. So I'm like, whateva. So the movie ends and the blanquita is like, "Oh my God, my purse is still here!" You believe that shit? That bitch think that because I'm Latina, I'm just gonna steal her shit! So I got mad fuckin' ghetto, I'm like, "Bitch, I'm not like that! And you should not be like, thinkin' that like all Hispanics are like that!" Bitch got the nerve to say to me, "Well, I've been robbed before." And I told that bitch, "Oh well, good for you; you lucky I'm in a good mood today 'cause I woulda robbed you and smiled at you while doin' it!"
I just heard this word for the first time today. I think it's ghetto for "white girl."
"So the movie ends and the blanquita is like, 'Oh my god! My purse is still here!'" (I did not make that up and that's exactly what I heard.)
