NYSF 

An acronym for the National Youth Science Forum. It is a forum in Australia where 144 17-year olds congregate at either Australian National University or the University of Western Australia and participate in activities of a science based nature. However, many social events occur as well and by the end of it, many students have formed close bonds, stronger than that of their families. The term has been adapted to identify those who have attended the NYSF, these are NYSFers.
