Cheese bus

Re Cheese bus
This phrase is perhaps linked to the 'Scottish' word 'cheesy'meaning 'corny or not cool'This is terminology which has evolved.

The Online Etymology Dictionary says "cheesy" in the sense of cheap or inferior derives from the Urdu word "chiz" for "a thing" which was picked up by British folks in India in 1818 and gradually evloved into the current meaning. Not that we discuss meanings of single words here.

So far I think "cheese bus" is strictly a Northern New Jersey urban thing that combines the color of the bus with the perceived indignity of going to school.
