Second, the diminutive version, reinita, is used to denote an attractive woman with fine manners.
Third, reinota, is used to refer to a voluminous woman for whom the most appealing trait is quantity (rather than quality): six foot hotties will always be reinotas.
Fourth, reinaje is a singular term that means a collection of an unspecified number of reinitas, reinas and reinotas.
In the market: ¿Ora no lleva aguacates reina?
[You ain't getting avocados this time my queen?]
En ese antro, pura reinita de la Ibero.
[In that club you find only fine-mannered hotties that attend expensive colleges.]
Me pase seis meses de huevos en Praga, rodeado de pura reinota.
[I spent six awesome months in Prague, surrounded by voluminous beautiful girls.]
En las fiestas de ese güey el reinaje es de alto calibre.
[In that dude's parties girls are always high caliber.]
In every case, referring to women as reinas is a speech figure meaning that guys are "at their service." In the image you can see a true reinita, Queen Gorgo from the popular movie "300."
