a new and increasingly popular maneuver in the sport of bodyboarding where a rider attempts to get up to dropknee, but immediately face plants instead.
a known variation of "pulling a Deon" includes "flailing about" and skidding down the face of the wave for a short distance, before getting pounded on the head by the lip of the wave.
man: "WOAH! That guy with the blue fins surfing the lefts keeps pulling a Deon!"
grom: "wowww.... so rad! i wanna be just like him :D "
