The term "Lost Boys" can refer to different groups depending on the context:

1. In J.M. Barrie's "Peter Pan," the Lost Boys are a group of boys who fell out of their prams when their nurse wasn't looking, and if not claimed within seven days, they are sent to Neverland. They live with Peter Pan in Neverland, symbolizing the innocence and freedom of childhood and the desire to never grow up. They are playful, brave, and sometimes naughty children who have no adult supervision. Key Lost Boys from the original story include Tootles, Nibs, Slightly, Curly, and the Twins. The boys eventually grow up or are adopted, except for Peter Pan, who remains a child forever.

2. The Lost Boys of Sudan refers to a group of around 20,000 young boys displaced or orphaned during Sudan's civil war in the late 20th century. Many of these boys fled their homes to escape violence, traveling long distances to refugee camps. Some later resettled in other countries including the United States, seeking safety and education.

3. "The Lost Boys" is also the title of a 1987 American comedy horror film about two brothers discovering their new town is inhabited by vampires, named after the Peter Pan Lost Boys in reference to eternal youth. This film spawned sequels and has a cult following.

Each usage highlights a distinct meaning—from a fictional group of children in a fantasy story, to a tragic historical group of refugees, to a pop culture film about vampires.
