Was "88" the name of a student rap group?

The controversy over High Tech High School's "88" tagged yearbook seemed to end in an impasse.

The school is reprinting the yearbook with an acknowledgment that this is a "teaching moment" for the district in "language and symbols" and a promise that going forward, the yearbook would be adequately vetted prior to publication. That's good.  Yet the Superintendent appears to stand by the original investigation which concluded that the "88" was a benign reference allegedly named after a North Bergen park, with no acknowledgement to offended families that it was an anti-Semitic hate symbol.  Can it be both?

Maybe, maybe not.

Possible insight into the "88" tag was uncovered in a deep dive on Twitter.  Several students debated the symbol's inclusion in their yearbook.

A fourth kid added:

Then later claimed:

For the record, I searched and have not found any record of this alleged "diss track" if it currently exists online.

But why do multiple students appear to know about it?

Note, there was no mention in the HTHS investigation of any student rap group named "88."  Just that "88" was "North Bergen parlance" for a park. 

For a true "teaching moment" in this matter of public interest and public concern, it wouldn't hurt for an independent review of what happened here.  A second opinion, if you will.
