A masturbation technique used by males where the guy bends over toward the floor gripping his junk in both hands. Then, with knees slightly bent he jumps repeatedly whilst keeping his hands the same distance off the ground--not necessarily in the same proximity to his body. Thus, as he jumps his junk will move in and out of his stationary, lubbed up hands.
"Dude, I so need to get in shape so I can finish the two handed yak stomp."
