Nicki and her friends hang out at a place they call the skate spot, which is a section of the park that is good for street skating. It is not a formal skate park.

Zines, or homemade magazines, experienced an increase in popularity in the 1990s. They were often photocopied and distributed to friends, creating a sense of community.
The phrase “talk to the hand” was a popular saying. It essentially meant “I’m not listening to you.”
December 31, 1999, was one of the most celebrated New Year’s Eves in history, marking not just a new year, but the start of a brand-new millennium.
