Used to describe a Latin woman with no refined tastes. Bad words easily flow from her mouth, she is sloppily dressed, and smells like armpit and beer. Speaks without thinking and beats her kids with her purse or her belt. Loose woman with no values.
Latin people's version of white trash.
"Esa vieja simplona apesta a pura cerveza."
"That old simplona stinks of beer."
"Me la heche ala vieja simplona."
"I shagged the old simplona."
