What is the guy in the background yelling in Episode 1?? Worldstop??

he's yelling "world star"

there's a hip hop website called "worldstar hip hop" which publishes videos from the streets ... what you are hearing is the trademark voice over on the videos "world star"

Seeing how I know very well what he is yelling, makes me crack up at this post. The times I’ve seen a character shout “world star” in a show or movie always amuses me, tho.

There was a time I wasn’t familiar with this lingo myself.
