La Flaca
When a Mexican or Mexican-American sees a super skinny girl at a party, they shout 'La Flaca' so loud it sounds like they're cursing her for being too thin.
'La Flaca! That girl’s got no hips!' I yelled like I’d seen her in a horror movie.
I screamed 'La Flaca!' at the girl like she had stolen my last taco.
I saw her and yelled 'La Flaca!' because she looked like a noodle in a dress.
