the kind of guy your mamma warns you about - just out for whatever he can get from a woman

is the term often used in the blues: low-down, dirty mistreater. Other possibilities are vampire, psychic vampire, a man who stops at nothing, a gold-digger, etc. etc. There are so many terms that you need to narrow it down a bit - is the sex part more important than the money? How old are the victims? Is he a power-monger, or is he a pimp, or is he a pretty boy preying on older women? The more precise you can be in your question, the better we can answer you.

One of the traffickers told her they were going to kill her baby. "I thought it was a joke," she said. "But two weeks later the woman trafficker told me to put the baby to bed and sent me on an errand. When I returned, she told me to pick up the baby and give it a bath. It was stiff. Afterwards, the talk in the neighbourhood was that the traffickers had killed it. Three days later they sent me back to work."

One common ruse that traffickers use is to marry a girl in a quick ceremony, then take the girl to India for sale to a brothel. One photograph showed a "border guard" looking a a birth certificate that turned out to be false; in front of her is a young woman wearing a shawl, with a Hindu married woman's red mark on her forehead. Behind her is a man, trying to rush by -- he was the young woman's trafficker.

lecherous prick

Just 2-3 days ago I heard a program on the radio (Mojo Radio) about women who get what they want by using mostly their beauty, charms and... well, whatever they have in addition to the above. :-)) They (women) discribed this process of getting what they wanted (mostly in career) as "sleeping their way to the top". Then they were asked a question: "Do you know any men that would do the same?" And the answer was very simple: yes! This is not a known though. This is also about a certain way to get what a person wants.
