"Are you struggling to obtain your legal rights? Nil Bastardum Carborundum." meaning, literally "
don't let the bastards get you down" or "
don't give up in your struggle against unfair treatment."
It is a phrase of made-up
words designed to sound like a traditional
Latin (the language of ancient Rome) motto as used by many schools, universities and similar organizations, also by wealthy high status families or anyone who aspires to such a condition. This type of made-up pseudo- (ie fake) latin is sometimes called cod latinor "pig latin" Compare with J.K. Rowling's motto for Hogwarts school Draco dormiens nunquam titillandus The wrong use of the latin-sounding
words is intentionally ironic and carries an implication of a lower class or self- educated person sticking it to "
the man", who presumably could afford a classical education.
