A snakeoiler is a preditorial person, in an exponential search for unsuspecting victims. As a financial planner or the like, the snakeoiler uses all his charm and selling skills to persuade his victims into parting with their hard earned money for distribution into dodgy investment vehicles. These investment vehicles usually consist of low growth and substantial ongoing fees. The snakeoiler is paid a pro rata fee from the companies who run the dodgy investments and this money is used to fund his lavish life full of woman, alcohol and travel to countries where his dollar, or should we say our dollar is stretched as far as it is possible. The snakeoiler can often be found shopping for snake skin shoes and cheap suits.
The snakeoiler is similar to a car salesman, but worse.
