The Slimeball is a character who has the most slippery slimy personality imaginable. Usually motivated by petty personal gain, the Slimeball is always trying to manipulate events around him in his favor and the people around him into viewing him in a favorable light. A defining characteristic of the Slimeball is a lack of class or sophistication. While some Slimeballs erroneously believe the opposite is true, there are an equal number who accept their crass nature. Above all and whether he consciously knows it or not, all of the Slimeball's actions are ultimately taken out of self-interest.

The Slimeball can appear under the guise of friendliness and the desire to help others, however depending on the story he can also be the Card-Carrying Villain with no attempt to conceal the fact. Sometimes the Slimeball is an Obstructive Bureaucrat introduced to harass the protagonists - his slimy nature will often be confirmed by some subtle attempt to manipulate the protagonists into doing what he wants them to. Only very rarely will he be above attempting Sexual Extortion against female protagonists if he happens possess something they desperately need.

The Slimeball's motivations and actions are usually directed towards the goal of personal gain, often monetary or of a sexual nature. While a Slimeball can also be a Magnificent Bastard villain or a Smug Snake, not every Slimeball has such grandiose ambitions, some preferring to simply make quick easy money or to influence others to like and trust them. The Slimeball who only harbors petty ambitions is almost always a Small Name, Big Ego and a Dirty Coward. When dealing with just about any person in authority with the strength to back it up, he will default to being a Professional Butt-Kisser. When his ambitions are sexual, he is usually a Casanova Wannabe. In many romantic comedies, the romantic rival for the protagonist will usually end up being recognized as the Slimeball by the end of the film. The Slimeball may also be a Miles Gloriosus, using tall tales of alleged courage and adventure as an attempt to be charismatic. The most common reaction from a protagonist after dealing with the Slimeball is the intense desire to take a shower.

Because most female antagonists are portrayed as either attractive or tough and aggressive, the instances of female Slimeballs are extremely rare.
