A latch-key kid is someone who goes to a public area (i.e a park, playground) because they have nothing else to do. They spend most of their free time there, and eventually learns the names of everyone who visits that area. May participate in activies such as frisbie, basketball, etc.
Latch-key kid Nathan likes to spend all his free time at the public gym to play basketball with all other latch-key kids.
