Josh Kerr absolutely rips on a surfboard. I should know, I was having a coronary in the announcing booth at The Quiksilver Pro NY surf contest last week when Kerrzy decided to go apeshit and turn his heat into a video part. These pro-model shorts are an undergarment of sorts. Meant to be worn under your board shorts to keep the boys in check. They act as a compression short. This can be very important if you suffer from the dreaded long nut* syndrome or if you are going anywhere that sea lice can sting you on your pee pee.
* From Urban Dictionary
Long Nut: when a man’s scrotum becomes stretched out over time and hangs lower than it should.
i.e.-you know you have long nuts when you get a temperature reading of toilet water whenever you take a number two.
potential causes: inadequate support for the hairy beanbag during impact sports
