- a person or thing that slides.
- a pitch similar to a curveball but one in which the ball rolls or slides, rather than spins, out of the pitcher’s hand and, like a curveball, drops and veers as it approaches home plate, sharply but with less of a curve: Johnson’s unhittable slider made him one of the best pitchers in the history of the game.
- any of several freshwater turtles of the genus Chrysemys, of North America, having a smooth shell usually olive brown with various markings above and yellow below: some, especially C. scripta, are raised commercially and the young sold as pets, rarely surviving to adulthood.
- a small burger on a bun: beef and lamb sliders.
