Hup, hup, down to the beach

Pentwater is a place of token sayings. However, few sayings reached the fever-pitch success of "Hup, Hup! Down to the beach!" Invented by AJ & Seth, it was so popular that it was placed on the 2001 T-shirts, an honor bestowed on no other saying from Pentwater. Unfortunately, its popularity was brief and it is hardly mentioned anymore. A graph is included below to illustrate its rise and subsequent fall from grace.
