I haven't seen School Daze in over 30 years but if I remember it was about warring frats/sororities at a HBCU. It was the Wannabes (light skin) versus the Jigaboos (dark with natural hair, Afrocentric style) and they belonged to different frats depending on the color of the skin. I remember a part where they sort of battled each other in song - "You're a wannabe- wannabe better than me" "You're a jigaboo .. (something about nappy hair or similar). I also remember the Spike Lee character being a virgin and his brothers chanting something about "pass the *****."
JBW= I think "just be white" blackpill looks theory, I think.
