What is what does esp mean?

ESP stands for Extrasensory Perception, which is a term used to describe the ability to perceive information through means other than the five physical senses (sight, hearing, touch, taste, and smell). This can include abilities such as telepathy (communicating with others without speaking), clairvoyance (seeing things beyond the range of normal vision), or precognition (knowing things before they happen). While some people believe in the existence of ESP, it is not considered a scientifically proven phenomenon.
