In high school before there was HG, there was, well... two groups that originated from different sides of Cabramatta. The Western Clan (Cabramatta West P.S), the Eastern Clan (Cabramatta Public P.S). Little habibs in year 7 they were, causing trouble with each other, while the girls had become friends with each other and yakked about how immature the boys were. The warfare only lasted for a year , when in 1998 the 2 clans began partying with each other. Fast forward to 1999, year 9 (or was it year 10???), the one giant clan finally got a name for itself:

HG: Happy Generation.
