p rocker
a guy who knows every secret in the universe but still can't remember to do his homework
My brother is a p rocker. He knows all the SCPs but still failed science because he drew a goat on the test.
I told my friend he was a p rocker. He said, 'I know everything, but I still f***ed up my math test.'
My friend's p rocker cousin knows every SCP but still got kicked out of the library for eating a sandwich.
