I believe UB stands for University at Buffalo [1] or more precisely State University of New York at Buffalo.

as someone who grew up in Texas, I was wondering WTF UB meant and how so many people seemed to know what it was. RPI I knew because I they sent me literature while I was in high school 30 years ago.

UB = undefined behaviour

RPI = Rob's Pairing Interview

I understanding wanting to avoid the former, but the latter is pretty good.
