【Cork】 RIDESTOREより
The cork is an advanced variation of a rotation, where you are not just spinning upright, but your body is actually spinning off-axis. Mid-jump you may do a frontside or backside 360 whilst your legs and board rotate upwards, so your upper body is below your board. For experts out there, performing corks will have you rotating upside down, which is pretty wild and difficult to comprehend.
