Streetkid, along with Nomad and Corpo, is one of the lifepath choices in Cyberpunk 2077 that dictates V's background during the game.
Street kids have lived most of their lives in Night City. They know the streets, the gangs, the slang, and generally what's going on in the "lower life" aspects of the city, which could present certain favorable opportunities later in the game.
Having previously left Night City for Atlanta, V helps out a bartender by settling a debt. The target is a high-end car, which other members of the Night City street life are eyeing up for themselves.
They say if you wanna understand the streets, you gotta live 'em. Gangs, fixers, dolls, small-time pushers - you were raised by them all. Down here the law of the jungle dictates the weak serve the strong - the only law in Night City you have yet to break.
