Blowing out a snot-ball when you're sitting on your board waiting on a wave. Usually by pressing on one side of your nose and blowing mucous directly into the sea, but also by blowing snot into your hand and flinging it away from you.
Brah, my nose started running while I was waiting on that set. Had to do a gnarlysurfer honk.
Midway thru happy hour at the local bar one girlfriend asked another where their other girlfriend went and was told " Oh, she took that hunky guy out to the car to make out, she's probably honkin' on bobo by now, lol"
