A slider can refer to different things depending on the context. Here are the different meanings of a slider:

• Slider pitch: In baseball, a slider is a breaking ball pitch that tails laterally and down through the batters hitting zone. It is thrown at a speed that is lower than a fastball, but higher than the pitchers curveball. The break on the pitch is shorter than that of the curveball, and the release technique is between those of a curveball and a fastball).

• Slider sandwich: A slider is an American term for a small sandwich, typically around 2 inches (5 cm) across, made with a bun. Sliders can be served as hors doeuvres, snacks, or entrées. They have become a popular game day appetizer in the United States. The name "slider" is believed to have been first used to describe the onion-steamed small burgers at White Castle restaurants).

• Slider grip: In baseball, the slider pitch is thrown with a specific grip. It is gripped like a two-seam fastball but held slightly off-center. On release, the pitcher uses the contact along the length of the seam and pulls downward to create spin. The slider uses the leverage of the seam rather than a wrist action to impart spin.

• Slider vs burger: Sliders and burgers are two popular meals in America. A burger is meant to be the main course, while the slider is a little more flexible in being able to be an appetizer if you stick to 1-2 or you can make it a meal by ordering a group of them. Sliders are also usually meant to be finger food rather than something you have to use two hands to hold. A burger can be the healthier option that is designed to be bigger and on its own. A slider can arguably play a more flexible role with meals.

In summary, a slider can refer to a pitch in baseball, a small sandwich, a specific grip used to throw a slider pitch, or a type of food that is smaller than a burger.
