Yeah, it's a ribbing we surfers give each other in California.
The "NORCAL" guys think they're hardcore. The only thing more hardcore about them is the amount of hair under their girlfriends' arms.
It's the SO-Cal surfers who consistently raised the bar throughout history, from wining world championships (Tom Curren) to Pipe Masters (Machado, Buran), to pioneering the North Shore (La Jolla Crew).
It's all in fun.
Nobody should get upset about it, as long as they understand that the SoCal guys rule.
