A gringa (white female) who desperately wants to be or be taken for a Latina. Often seeking out the company of Latino gang members or drugs dealers (thus the "juana-be" suffix instead of the standard "wannabe") to further the image. See "Weeds" on Showtime for a popular fictional example.
That chick over there in the sequined shirt calls herself Juanita, but her real name is Joanne and she's from the suburbs. She's just another latinajuanabe looking to steal one of our men.
