A bimbo. Sexy and not necessarily stupid girl, with legs up to her shoulders, micromini skirt aka dopičnjak, financed by, or more often in search of a such a financier, someone with a jeep (that's what they call SUVs here), pistol and an empty position of the sponsored girl.
Didn't exist as a phenomenon or a word until the nineties. Then, with many other career choices vanishing, became prominent.
