...Actually, nothing jumps out at me at all. I'm not sure what to make of it. Why do they read high school kid out of that?

Street credit. Usually referred to as social status in the neighborhood and local friend groups. Usually used by rappers and African American neighborhoods. However, people living in these neighborhoods don't actually say this today. Typically middle and high school students hear this on TV/radio and use it in their own (usually upper/middle class) circles to increase their social status.
Zero refers to zero street cred. Username plays a pun, the the user actually has zero cred. Again, only used by people outside the "street" aka in middle and high school. Also 98% chance OP is male. I'd say 50-60% white, sice we're on HN. With the other 40-50% being Asian or Indian.
In summary, yes, usernames tell you a lot.

But site demographics tell you a lot more!
Wiktionary defines "street cred" as:
> Credibility among young, hip urban dwellers; particularly important in the hip-hop and rap scenes.
Google defines it somewhat more tersely as:
> acceptability among young black urban residents
Given that the user name says the user has no street cred, it's ironic that people would assume the user is "urban".
I don't think so. If they weren't “urban” it wouldn't be relevant at all—no streets.
