I always heard the phrase "honor roll" as "on a roll". It made sense to me that if a person had mostly B's they would get a certificate saying "B On a Roll" like, "hey you're getting a lot of b's you're on a roll".
When my neighbor got a D on his report card, I asked him if there was a D "On a roll" and he punched me. Lessons learned the hard way.
