A sanky panky is a man, usually but not always a resort worker, who will persuade a foreign woman to fall in love with him (not difficult as they are very good at what they do), with the sole purpose of extorting as much money out of her as he can. He will usually have several different foreign women on the go and the good ones make an extremely good living out of what they do. They should not be confused with the newly identified species, the narcissistic Dominican (not my definition but from Canadian psychologists) who is a Dominican who doesn't give a sh*t about the woman he marries, but only requires a visa to get to the US, Europe or Canada, and once there usually leaves the woman to make as much money as he can to send back to Dominican wife or to meet another of his conquests in the same country, or just to hang out with the Dominicans there.
