I get the difference my dear. But you can argue sankies are all over not just in the DR, correct? I mean a sankie in the DR have different objectives.e.g visa, flight from the country, etc etc One can argue that there are many sankies out there who get involved in relationships to gain for themselves, whether it's to move up the social ladder, for economic or work related gains, or what have you. People can be selfish and out to gain for themselves at the expense of hurting others in the process
I'm not sure of the point you want to make, but if it's of any interest to you, sankies are unique to the DR.
It is a name that has origins, coming from "hanky panky".
The locals, hearing this expression rather frequently, when they were working the female tourists, knew it had something to do with them, but couldn't quite pronounce the words, and would say, "sanky panky", which quickly became the nickname for the DR gigolos.
With time and for practical reasons, it got shortened to "sanky/sankies".
Thus, sankies, are unique to the DR.
In other parts of the world, they would be called gigolos.
Now that we've cleared that up, I believe the point of this thread is to do with why sankies are seen in a negative light.
2Leftfeet has answered the question, and I can assure you, it could not have been a more precise answer, but if you would like some further colour, let me put it this way.
A sanky is a lying, cheating, kniving piece of shyte with no morals and ethics.
This is why they are seen in a negative light.
End of story.
