What is walk on?

"Walk-ons" generally refers to individuals who join a sports team without being recruited or formally scouted. They simply show up and express interest in joining the team, and their performance during tryouts determines whether they are accepted or not. Walk-on players typically have to work harder than other players to earn recognition, playing time, and full scholarships, but many walk-ons have gone on to have successful athletic careers. Additionally, the term "walk-on" can also refer to actors or extras who appear in a movie or TV show without a formal audition or speaking role. In this context, they are typically paid a flat fee or hourly wage to appear in the background of a scene.
