beemo
n.— «Neither dictionary mentions “beemo,” the mildly pejorative word for a zealous student that haunted my 1970s childhood in central Massachusetts.» —“Pixies, Sheilas, Dirtbags and Cougar Bait: Modern Slang” by Caleb Crain Nation Dec. 10, 2008. (source: Double-Tongued Dictionary)
A similar term I used growing up in New Jersey in the 1970’s was “Bomar”… this came from a high-end calculator of the time called a Bomar Brain, so the term denoted a brainiac of a kid. BTW, I didn’t find “Bomar” in this dictionary, so I may need to add it.
