A woman from Central or South America who is on the prowl for an American or European boyfriend.
All the gringo hunters hang out in the Irish pub, it's a great place to get laid.
A woman who looks for foreigners in the internet or anywhere else 'with passport in one hand and a condom on the other hand' where sex tourism is not restricted only among prostitutes but also among middle-class college students trying to find a better way of life trying to live in another country. Or some of them do it only for the pleasure of improving their language skills.
-Man, she will not look at you when she's just looking for a chance to get rid of this country with a foreigner. Forget it !!!
- Does she not like local guys???
- No, she's just a gringo hunter !
